(25 pts) The 50-lb block rests on the smooth surface. A force F = (40+s²) lb, which s is in ft, acts on the block in the direction shown. If the spring is originally unstretched (s = 0) and the block is at rest, determine the power developed by the force the instant the block has moved s = 1.5 ft. F. 30° k = 20 lb/ft wwwwww
