A 15.4 kg block is dragged over a rough, horizontal surface by a constant force of 187 N acting at an angle of angle 26.6 above the horizontal. The block is displaced 9.41 m and the coefficient of kinetic friction is 0.14. 15.4 kg μ = 0.14 187 N 26.6 Find the work done by the 187 N force. The acceleration of gravity is 9.8 m/s2 .
