The figure below shows a force versus position graph for a spring/block system. If Fs=160N and the block is released at x = 12 cm (not shown on figure) how much work is done on the block by the spring as the block goes from x = + 8.0 cm to x = + 5.0 cm. HInt: Determine k from the graph. Don't forget to convert from cm.

A small box with mass m is released from rest by a spring compressed a 3. distance d. The spring constant is k. After being released, the object slides along a frictionless track. What is the speed of the box when it reaches point B at height h/2? What must be the value of d so that the box comes to rest at the top of the track at point C? Law B h m Application A
The box located at y =3.5 m is initially compressing a spring at a certain distance. When the spring was brought back to equilibrium, the box sled onto the rough incline, reached a frictionless horizontal surface and continued to move until it encountered a very rough surface where its motion halted at the end of the 5-m surface. Calculate the: A. compression distance of the spring to reach the end of the track B. speed of the box at the start of the frictionless surface K=3000N/M compressed mass = 10 kg 3. 5m Mx=0.9 frictlonless
