A 2.5 kg crate falls from a height of 3.0 m onto an industrial spring constant of 2.5x10^5 N/m. At its Greatest compression the reading on the scale (in Newtons) is:

A spring elongates by 1.5 cm because of a force of 15 N. Therefore the spring constant should be O 1000.0 N/m O 10.0 N/m 100.0 N/m O 10,000.0 N/m

An object of mass 0.5 kg is propelled up an incline of angle 17 degrees by a spring with a constant of 11.4 N/m. The horizontal surface is frictionless. The coefficient of kinetic friction between the block and the incline is 0.12. If the spring is compressed by 0.6 m, how high (h shown on the figure) will the object go? Answer in m with two decimals. k, x IM 1-?

A spring rests at a length of 0.5 m and is pulled to a length of 2 m. It has a spring constant of 3 N/m. What is the Eel of the spring when stretched?

A mass of 10 kg falls from a height of 1m on a spring and compresses it by 0.25 m. What is the spring constant of the spring?

An object of mass 6.25 kg slides down a hill of height 21.1 m. At the bottom of the hill is a spring with spring constant 53.6 N/m. How far is the spring compressed when the mass comes to rest? Assume the mass starts from rest at the top of the hill. Give your answer in meters to three significant figures.
