Chelsea is pushing a 5.0 kg resting block with 150 N of force, which is directed 20 degrees above the horizon. Chelsea let go of the block after pushing it for 2.0 m. Then the block slides on the track and compresses the huge spring at the right end. The spring constant is 3000 N/m. There is no friction.

a) Find the work done on the block

b) find the maximum compression of the spring when the mass is stopped

A 350-g block is dropped onto a vertical spring with spring constant k =110.0 N/m. The block becomes attached to the spring, and the spring compresses 50.6 cm before momentarily stopping. The speed just before the block hits the spring is 8.4 m/s. The work done by the spring force is -14.1J. The work done by weight is 1.74 J. If the speed at impact is doubled, what is the maximum compression of the spring

1) A block is released from point A and it slides down an incline (theta = 30 degrees) where the coefficient of kinetic friction is 0.3. It goes 5m and hits a spring with a spring constant k = 500 N/m. While it is being acted upon by the spring, assume it is on a frictionless surface. a) How far is the spring compressed? b) How far does the block go up the plane on the rebound from the spring?...

A horizontal force of 60.0 N is applied to a 3.00 kg block as the block slides a distance of 0.500 m up a ramp. The ramp is inclined at an angle of 30.0◦ and the coefficient of kinetic friction between the ramp and the block is 0.600. If the block is initially at rest, how fast is it moving at the end of the displacement? Please make answer very detailed

A 0.2 kg block compresses a spring of spring constant 1900 N/m by 0.18 m. After being released from rest, the block slides along a smooth, horizontal and frictionless surface before colliding elastically with a 1.4 kg block which is at rest. (Assume the initial direction of motion of the sliding block before the collision is positive.) A: What is the velocity of the 0.2 kg block just before striking the 1.4 kg block? B: What is the velocity of...
