Superman Definition and 31 Threads

I’m writing some stories about a superhero flying brick; similar to Superman in that he has superspeed as a power. He has a problem in that he has no indestructible suit like Supes employs. However, some friendly advanced aliens presented him with a skinsuit that can handle speeds (at sea level)...

[Moderator's note: Unnecessary introductory statement deleted.] There's a comic where Superman breaks out/shatters chains that were designed to haul stars across the galaxy - Let's say these chains were made to pull (our) sun What tensile strength would a chain need to help pull our sun without...

Comic is Superman/Batman #80 Superman explains that virtual particles are always spontaneous generated And that he's using his heat vision to (excite) the vacuum in order to accelerate the process. He's generating more virtual particles So my question is, how much energy or heat did...

ok i have a simple enough scenario that i need a hand with solving. first off just to say, i don't know how to do the math for it so maybe someone here could help me out. basically has to do with finding the top velocity of an object with a certain force applied. all in a vacuum and without any...

In Action Comics #867, Superman survived the explosion of a sun What I would like to know is, how much energy was he exposed to? - I know there's the Inverse square law to consider - And I know because of that, he did not get hit by the entire energy of that explosion because his surface...

After hearing an argument on the cutting power of Wolverine, I began to wonder "could Wolverine cut, and possibly kill, Superman?" Wolverine has one of the sharpest, and strongest, cutting implements in the Marvel universe, so could he hurt the Man of Steel?

Hi, How does Superman fly? Does he emit gravitons or does he control the spacetime curvature since he doesn't have any jet or wind based propulsion system?

Homework Statement The original superman leaps into the air to land on an 85.5 m high building. What was his intial velocity? d = 85.5 m v2 = 0 v1 = ? a = 9.8 m/s2 (I'm not sure about this one so I just used acceleration due to gravity) Homework Equations v2 = v1 + 2ad (?) The Attempt at a...

In a Superman comic Superman drops a bomb into a sun eater and outruns the explosion, which is 50 times the size of Kepler's supernova. He is hit by the electromagnetic shockwaves but manages to fly out of the way of the wall of radiation. What type of energy did he absorb? What do...

I know that you probably get tired of weird questions like this so I apologize in advance. I was thinking about length contraction in special relativity. I was thinking if superman was moving towards a basket ball at close to the speed of light when he passed it from his frame of reference it...

I'm writing a novel which has as a protagonist a super-powered being, like in the comics (only he is the sole such critter in the universe). Like Superman he has the ability for flight through space, but he cannot take any matter, baryons, with him. I'm hoping some astronomy experts could help...

When I was younger, I used to imagine myself fighting bad guys and saving the world. I still do, to some extent. But now when I think about being a superhero, I think about time sharing my unique skillset to the academic and space community. I think I would fly to Europa and break through the...

Homework Statement I need to locate the coordinates if a point of intersection x0,y0,z0 of a plane with equation 2x+y-z=0 and a line that is perpendicular to that plane and passes through a point G(2,1,0). Homework Equations and I understand that this is a normal line and a plane so...

hi, can some one give me an outline of how to solve the following question? thanks Superman (mass=84.0 kg) must fly into a train (mass = 18079 kg) traveling at 75.0 km/hr to stop it. Calculate the minimum time Superman must take to stop the train, if the passengers experience an average...

Homework Statement Superman must stop a 120-kmh train 150m to keep it from hitting a stalled car on the tracks. If the train's mass is 3.6 x 10^5 kg, how much force must he exert? Compare to the weight of the train (give as %). How much force does the train exert on Superman?" Homework...

Homework Statement This is a semester review. I am having trouble starting the second part of this question. It is well-know fact that Superman is "faster than a speeding bullet, more powerful than a locomotive, and able to leap tall buildings in a single bound." Assume his mass is 100kg. The...

In the movie, when superman flies near light speed, he manages to reverse time? Was the story-line just completely off from a physical perspective or is there some truth to this phenomenon? I understand that time would slow down for superman from a human's perspective. Maybe I just didn't...

Homework Statement Superman leaps in front of Lois Lane to save her from a volley of bullets. In a 1-minute interval, and automatic weapon fires 150 bullets, each of mass 8.0g, at 400 m/s. The bullets strike his mighty chest, which has an area of 0.75 m2. Find the average force exerted on...

Homework Statement As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 32.0. How fast is the...

Homework Statement A.) Find the speed at which Superman (mass=79.0 kg) must fly into a train (mass = 17026 kg) traveling at 70.0 km/hr to stop it. B.) Running into the train at that speed would severely damage both train and passengers. Calculate the minimum time Superman must take to stop...

Homework Statement Determined to test the law of gravity for himself,a student walks off a skyscraper 200 m high, stopwatch in hand and starts his free fall (zero initial velocity. Five seconds later, superman arrives at the scene and dives off the roof to save the student. a.) What must be...

did anyone see this movie? and what's your opinion on the black hole that was shown at the end of the beginning credits? for those of you who didnt see it and will not. a black hole sucked up a sun and after that, there was a explosion of white light which i assumed was the hawking radiation.

OK, I'm giving away the ending, so don't say I didn't warn you...At the end, Superman lifts Luthor's new landmass into space. I did some rough hand calculations to figure out how much energy Superman had to use to lift the island into space. Judging from the scale presented in the movie, I'm...

I can't figure this one out. Please help. It is well known that bullets fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman's chest with bullets of mass m = 1.8 g at a rate of R = 200 bullets/min. The speed of each bullet is v = 460 m/s. Suppose the bullets...

I'm back once more because of another problem that is driving me nuts. I've been trying to do this one for a long time. I'm posting the previous problem because it has relevant information and then bold typing the problem I'm confused on. ----Find the speed at which Superman (mass = 79 kg)...

SUPERMAN (Cristopher Reeve) has died today. So I'm very sad :frown: . I was one of that children who were dreaming all nights of being Superman and flying all over the world. I usually went with my mother to the cinema to see each of his films, he was a part of my childhood. It was a pity to...

Could anyone explain the why superman whizzing around the Earth turned back time ?

Have any of you seen the NBC/American Express specials featuring Seinfeld and Superman? They can be seen http://www.jerry.digisle.tv/room.html if you missed them. Jerry Seinfeld - best ever.
