Consider the crate below, released from rest. The mass, H and h are known, as is L. The two angles are also known. The surface with friction has known coefficients of friction and us. The spring constant of the spring is k (also known). no friction friction no friction Using energy, calculate the maximum height the crate reaches on the right slope, assuming that it is still moving when it hits the spring. Note: This question is not as hard...

2. A 10-kg block is released from rest at point A, as shown below. It slides along a track that is frictionless except for a "sticky" part between points B and C. After its motion along the track, the block hits a spring with spring constant 1500 N/m. It compresses the spring 0.4 m before momentarily coming to rest. 3.00 m 6.00 m-. We have seen in class that when an object moves along a rough surface, the force of...
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...

1 Warm-Up Questions 1 A block of mass m = 3 kg is dropped from the top of a half-pipe (half-circle) of radius R = 2 m starting from rest. The surface of the incline does have friction. If the block comes to rest at half of its initial height, how much work was done by friction? Work: 2 Initially, a ball of mass 0.4 kg is compressed by a spring, with spring constant k = 980 N/m, by a...

4.[1pt] A block of mass m - 6.10 kg is released from rest at a height of H- 10.00 m on a curved frictionless ramp. At the foot of the ramp is a sring whose spring constant is k -455.0 N/m. What is the maximum compression of the spring, x? Answer: Submit All Answers 5.[lpt] After the spring reaches its maximum compression, it pushes the block backwards. What is the maximum height reached by the block? Answer: Submit All Answers
An object of mass 3kg is released from rest from a height h of 13 meters...
An object of mass 3kg is released from rest from a height h of 13 meters above the ground on a ramp. The object then slides down along a horizontal surface along a distance of d=20 meters where friction is present (\mu_s=0.5 and \mu_k=0.2), and compresses a horizontal spring initially unstretched until it finally comes to rest. If k=300N/m, by how much does the spring compresses (maximally) upon impact?

A block of mass 10kg is released from rest and slides down a frictionless track of height h 5m above a table (see figure). At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with spring constant k 10k the acceleration of gravity to be 9.81 The maximum distance d the spring is compressed is
A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released...
A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...
