A 18.8 kg block is dragged over a rough, hor- izontal surface by a constant force of 77.6 N acting at an angle of 35? above the horizon- tal. The block is displaced 10.8 m, and the coefficient of kinetic friction is 0.139.
The acceleration of gravity is 9.8 m/s2. If the block was originally at rest, determine its final speed.
