A0.62 kg mass is held against the a compressed spring and released from rest. The linear spring is positioned horizontally across a frictionless surface. It has a spring constant of 609 N/m and is initially compressed by a distance of 0.134 m from its equilibrium position. With what speed does the mass leave the spring?

Suppose a block of mass 0.9kg is is held against a spring with spring constant 1.0 × 103N/m, compressing it to a distance of 0.15m. What’s the fastest speed the block can have after it is released and the spring pushes it away?

A 5.8 × 105 kg train is brought to a stop from a speed of 0.85 m/s in 0.57 m by a large spring bumper at the edge of its track.  What is the force constant k of the spring in N/m?

A block of mass ?=3.80 kg slides along a horizontal table with velocity ?0=1.50 m/s. At ?=0, it hits a spring with spring constant ?=41.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.

A 0.28 kg mass is held against a compressed spring with a spring constant of 2,446 N/m. The mass is initially at rest upon a horizontal surface and the spring force is directed parallel to the plane of the surface. If the coefficient of kinetic friction is 0.716, with what speed does the mass leave contact with the spring if the spring is initially compressed by 0.068 m?

A 1.44 kgkg piece of cheese is placed on a vertical spring of negligible mass and force constant kkk = 1800 N/mN/m that is compressed 19.0 cmcm. When the spring is released, how high does the cheese rise from this initial position? (The cheese and the spring are not attached.) Express your answer in meters.

A 4.4 × 105 kg subway train is brought to a stop from a speed of 0.55 m/s in 0.54 m by a large spring bumper at the end of its track. What is the force constant k of the spring in N/m?

A 2.0 kg ball is launched by means of a vertically oriented spring with spring constant k = 16.0 N/cm. The spring is compressed 10.0 cm before the launch. (a) What is the maximum speed of the ball during this launch? (b) What is the maximum height the ball reaches? (Consider y = 0 to be the equilibrium height of the spring)

A block of mass 2.9 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 470 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 13°.  a) The block, starting from rest, slides down the ramp a distance 54 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes to momentary rest?  b)  After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring?  c) What is the change of the gravitational potential energy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?

A 2.85 kgkg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0350 m. The spring has force constant 865 N/mN/m. The coefficient of kinetic friction between the floor and the block is 0.390. The block and spring are released from rest and the block slides along the floor.   1)What is the speed of the block when it has moved a distance of 0.0200 mm from its initial position? (At this point the spring is compressed 0.0150 m.)
