The 10-lb block has a speed of 4 ft/s when the force of F = (8t2) lb is applied. Determine the velocity of the block when it moves s = 30 ft. The coefficient of kinetic friction at the surface is s = 0.2.

QUESTION:

The 10-lb block has a speed of 4 ft/s when the force of F = (8t²) lb is applied. Determine the velocity of the block when it moves s = 30 ft. The coefficient of kinetic friction at the surface is _s = 0.2.
