Question

A 1.65kg block slides with a speed of 0.850m/son a frictionless horizontal surface until it encounters a spring with a force constant of 692N/m . The block comes to rest after compressing the spring 4.15 cm.

Part A

Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of 0 cm.

Enter your answers numerically separated by commas.

Part B

Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of 1.00 cm.

Enter your answers numerically separated by commas.

Part C

Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of 2.00 cm.

Enter your answers numerically separated by commas.

Part D

Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of 3.00 cm.

Enter your answers numerically separated by commas.

Part E

Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of 4.00 cm.

Enter your answers numerically separated by commas.

Explanation / Answer

KE of the block=mbvb2/2= total mechanical energy of the system in all the cases

PE of spring=kx2/2 value of x is different in all the cases
