Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 50 N/m attached to a 50-kg block in an incline (©=30°). With the
spring initially at equilibrium position, the block was pushed 0.3 meters up the incline by a 50-N external force applied parallel to the path. The coefficient of kinetic
friction is 0.30.
d) How much work is done by the block (in Joules) on the spring?
e) How much work is done by the applied push on the block?
f) How much work is done by friction?
