A 10.0 kg block is dragged overa rough, horizontal surface by a 73.0 N force acting at 20.0° above thehorizontal. The block is displaced 4.50 m, and the coefficient of kinetic friction is 0.300.
a) Find the work done on the block by the 73.0 N force.b) Find the work done on the block by the normal force.c) Find the work done on the block by the gravitational force.d) What is increase in internal energy of the block-surface systemdue to friction?e) Find the total change in the block's kinetic energy.
