A wooden block weighing 10 lb is dropped from a height of 4100 ft with no velocity. As it falls, the load encounters air resistance numerically equal to v/7.5 (in pounds), where v denotes the velocity of the load (in feet per second). Find the (a) the limiting velocity for the load and (b) the time required for the load to hit the ground.
