A 300 lb block is in contact with a level plane whose coefficient of kinetic friction is 0.10. If the block is acted upon by a horizontal force of 50 lb., what time will elapse before the block reaches a velocity of 48.3 ft/sec starting from rest? If the 50 lb force is then removed, how much longer will the block continue to move?
