How do I solve part a and b

(20 pts) A 7.00-kg block is pulled 5.30 m across flat ground by 34.2 N force Fi directed at a $5.0" angle above the horizontal. A frictional force of 10.2 N acts against the motion. The initial velocity of the block is 2.22 m/s. USE ENERGY to solve this problem. FI a) What is the total work done on the block? b) What is the final kinetic energy of the block
