I have a problem I cannot figure out. It asks to calculate the spring constant when given a spring hung from the ceiling, a 0.497 kg block attached to the free end of the spring. The block is released from rest, drops 0.12 m before coming momentarily to rest. How do I calculate the spring...

For some reason, my spring constants are all screwy. an example Masses (Newtons) .049 .098 .196 .294 .490 Displacement (kg) .006 .019 .035 .055 .090 and the line i got was Mass=.188d-.001 doesnt that mean that the spring constant is .188 N/m? that doesn't make any sense...

Hello, I'm having some problems with the spring constant "k" together with Hookes law. U=1\2kx^2 Could someone please explain how you get that integral? If you insert it in a diagram and calculate the area as a triangle you would get 1/2kx. Where does the ^2 come from?

Hello: I'm stuck on this following problem. [FONT="Fixedsys"]A spring gun, held horizontally 1.6 meters above the ground, fires a 0.07 kilogram ball so that it lands a horizontal distance of 2.3 meters away. If the gun is pointed straight up, and the same ball is fired, how high (in meters)...

I received a spring constant on the problem below to be .005 N/m. I was wondering if this was even possible? When I got the frequency in the next part of the question, the frequency made sense, but i never thought a spring constant could come out to be so small. A small fly of mass...

A plane weighing 220 kN (25 tons) lands on an aircraft carrier. The plane is moving horizontally at 64.0 m/s (141 mi/h) when its tailhook grabs hold of the arresting cables. The cables bring the plane to a stop in a distance of 84.0 m. (a) How much work is done on the plane by the arresting...

The length of a spring increases by 6.90 cm from its relaxed length when a mass of 1.10 kg is suspended from the spring.What is the spring constant? so I know that ultimately i use hooke's law which is F=kx but how would i figure out F if i only have the mass? I can't do F=ma b/c i...

A ping-pong ball weighs 2.5x10^-2N. The ball is placed inside a cup that sits on top of a vertical spring. If the spring is compressed .055m and released, the maximum height above the compressed position that the ball reaches is 2.84m. Neglect air resistance and determine the spring constant...

is the same as the spring constant on Earth right? My reasoning is that since Force is directly proportional to displacement, the k would remain the same. But we don't know that k is constant so I don't think that is a solid proof...

I got a question. If a mass hangs motionless from a spring, what is the force exerted on the mass by the spring in terms of the spring constant, k? So I was thinking when a load of mass m is used on the spring it will stretch by a distance x, and as the extention is directly propotional to the...

A spring scale is stretched 10 cm when a force of 15 N is applied to it. How far apart should adjacent 1.0 N marks be on the scale? Why would 1.5 cm not be correct? Force= Spring Constant* Change in spring from rest 15n=k*10 cm k=1.5

In a physics lab we put weights on the end of a spring and measured how far the spring stretched. We attatched the weight to the spring with a hook that looks more or less like ? and the weights stack on the bottom. To make it easier, i just measured from the bottom of the hook to the floor...

A mass of 100 g causes a vertical spring to stretch by 2.0 cm. a) find the spring constant of the spring in N/m: No picture was given to me. Ok I am not sure if this is the formula to find spring constant so is it: k= mg/x and if so the answer is k=(100)(9.81)/2.0 cm k= 490.5 N/m...

I need to calculate a spring constant using measurements from a Hooke's Law Apparatus, a spring, and some weights. Frankly, I have no idea what I need to do. I've taken the measure ments, and discovered the formula F=kx, where F=Force, k=spring constant, and x=the compressed distance. I'm not...

Hi, I'm new round here and I hope you will forgive if this has already been asked. I've tried searching extensively, but can't quite find it. I found something very similar though, which I'll include. It is common knowledge that if you stretch a rubber band it warms up. Does this also...

Hi, I am trying to figure out a question in first semester physics... I have a different but similar question that I have the answer for that I am trying to work to figure out the process for the other question. What is the spring constant k of a spring designed to stop a 1300 kg car traveling...

You are asked to design a spring that will give a 1160 kg satellite a speed of 2.85 m/s relative to an orbiting space shuttle. Your spring is to give the satellite a maximum acceleration of 5.00g. The spring's mass, the recoil kinetic energy of the shuttle, and changes in gravitational potential...

In springs, when two springs are combined in series why is the total spring constant of the system 1/2k, and when three springs are combined in parallel, why is the total spring constant 3k?

Help - Formula for combined spring constant. Hey, I was wondering if anyone can help me with the formula to calculate the combined spring constant of two springs stuck together (end to end). This is as far as I've been able to figure it out lol, I can't wrap my head around this formula. The...

with no friction- what spring constant would fire a 10 g mass to a height of 100 m. the spring is compressed to 10 cm. i know k=F/x but i don't know how to find the force for this problem, because i need to find the acceleration and there is no time unit given. any help?
