A constant force does 12.0 Joules of work pushing a 350 gram block a distance of 2.5 meters up a ramp. The block starts from rest and reaches a speed of 4.75 m/s after being pushed for 2.5 m. The block’s potential energy increases by 5.0 J as it travels this distance. (a) What is the net work (also called the total work) done on the block? (b) What is the coefficient of friction between the block and the ramp?
