Find the resulting kinetic energy and speed of the block

Reference no: EM13316819

A spring has of constant k=1200 N/m is compressed by 8.0cm. A 2.5kg block is placed against the compressed spring. There is a kinetic coefficient of friction Mk=0.23 between the block and the surface.

a. what are the resulting kinetic energy and speed of the block?

b. If the spring is compressed twice as much, by what factors do (i) the kinetic energy and (ii) the speed increase?
