A 10.0 kg block sliding on a frictionless horizontal surface at 7.00 m/s hits a spring that is attached to a wall. The block compresses the spring and momentarily comes to rest. The spring has a spring constant of 5000 N/m. a) What is the net work done on the block? Identify the force(s) doing work. b) How much does the spring compress before stopping the block? The block rebounds back off the spring without energy loss. The block then slides over a level surface with a coefficient of friction of 0.20. The block takes 10 seconds to stop from the time it encounters the friction. c) What is the net work needed to stop the block? Identify the force(s) doing work. d) How far does the block slide on the friction surface before stopping?
