Question

A 15.2 kg block dragged over rough horizontal surface by constant force of 124N acting at an angle of 34.9 degrees above the horizontal. The block is displaced 37.8m. The coefficient of kinetic friction is .171. Acceleration is 9.8 m/s^2.
Find the work done by the 124N force.
Find the magnitude of the work done by the force of friction.
Find the work done by the normal force.
