A 10.0 kgblock is dragged over a rough, horizontal surface by a 84.0 N force acting at 20.0° above thehorizontal. The block is displaced 6.00 m, and the coefficient of kinetic friction is0.300.

(a) Find the work done on the block by the 84.0 N force.

(b) Find the work done on the block by the normal 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.
