Question
2. You push a 2.0 Kg block against a horizontal spring (the spring constant is k=200 N/m)
compressing it by 15 cm. Then you release the block and the spring sends it sliding across a
tabletop. The block stops 75 cm from where you released it. (a) Find the work done by the
spring force as it pushes the object. (b) Find the work done by frictional force acting on the
object. (c) Find the work done by all the forces acting on the block. (d) What is the
coefficient of kinetic friction k?
