Suppose you are in a warzone. You are in a concealed position and there is only one enemy soldier nearby. Both you and the enemy soldier are conscripted soldiers, neither desired to join the army in the first place. Also suppose that this will be the enemy soldier's last day in active combat...

Force Question - Still want another oppinion! A man pulls a cart on a friction fee surface by means of a pulley and rope. He pulls the rope at 600 N. Now replace the man's action with an iron weight of 60 kg so that it is attached to the end of the rope. The cart is again set in motion. Is...

If you have two particles that are even billions of light years away from each other, is there any gravitational pull between then? (Considering the possibility that there is nothing else in the universe)

Anti-Kerry vets won't pull attack ads

I'm a _n^e_w^b_i^e (that looks cool :redface: ) in physics, and have many doubts about the current model of gravity. I'm having a hard time viewing gravity as a pulling force. To me, it makes no sense. There is a new proposal, although very little have accepted it, on how gravity works...

Pull of Gravity...Where it starts? hi... Juz curious... when does the gravitational pull of Earth starts? eg: Let's say a comet/ a space rock ...It will travel slowly in space but once it is caught by gravity, it will accelerate, right? Yeah... so when does that happen.What distance from...

I was just thinking, and gravity, is the only invisible force that "pulls" everything else i can think of, besides magnetism, is a "push". can anyone else think of anything?

Quick questions for you astrophysicists out there: At what velocity do objects typically "fall" towards the galactic center? Or are we talking a positive acceleration? Assuming the sun were to survive long enough to reach the center, which it of course won't, how long would it take? Or do...

Please Help! Tension Pull problem w/friction Hello all, I am having a bit of trouble on this for some reason. On a horizontal plane, a 10kg box and a 20kg box are tied together by a rope, and the 20kg box is being pulled by another rope with a force of 200N. The coefficient of friction is...

I need to calculate the force required to pull a copper ball radius 2.00cm upward through a fluid at the constant speed 9.00cm/s. The drag forse is to be proportional to the speed, with proportionality constant .950kg/s. Ignore any boyant force. What I did so far was figure out the resistive...

what minimum horizontal force is needed to pull a wheel of radius R and mass M over a step of height H. force is supplied at center of wheel. ?

Q: There is a mass of a mass A (2kg ) sitting on top of a mass of B ( 4kg), which is sitting on top of a mass of C(3 kg). The static friction between A and B is .5; and between B and C is .5 and between C and the ground is .8. Mass B is tied to the wall. What is the minium force required to...
