A 14.1 kg pumpkin is placed on a vertical spring of negligible mass and force constant k = 2100 N/m that is compressed 31.0 cm. When the spring is released, how high does the pumpkin rise from this initial position? (The pumpkin and the spring are not attached.)

You place the spring vertically with one end on the floor. You then lay a 1.60 kg book on top of the spring and release the book from rest. Find the maximum distance the spring will be compressed.

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 child's toy consists of a piece of plastic attached to a spring (as shown in Figure). The spring is compressed against the floor by 2.00 cm, and the toy is released. If the toy has a mass of 100 g and rises to a maximum height of 60.0 cm, estimate the force constant of the spring? Copyright © 2009, Raymond.

A block of mass 0.259 kg is placed on top of a light, vertical spring of force constant 4 800 N/m and pushed downward so that the spring is compressed by 0.108 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise? (Round your answer to two decimal places.)

A 120 g arrow is shot vertically from a bow whose effective spring constant is 430 N/m. If the bow is drawn 67.9 cm before releasing the arrow, to what height does the arrow rise?

A cannon with a spring constant of 147 N/m is compressed by 20 cm to shoot marbles of mass 30 g. What is the farthest distance that it can shoot without hitting the top of the ceiling that is 3.0m above the ground?

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 block of mass 0.240 kg is placed on top of a light, vertical spring of force constant 4 975 N/m and pushed downward so that the spring is compressed by 0.107 m. After the block is released from rest, it travels upward then leaves the spring. To what maximum height above the point of release does it rise? (Round your answer to two decimal places.) 4.0 ☑ m

A 7.00 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.900 m by a large spring bumper at the end of its track. What is the force constant k of the spring (in N/m)?
