Include air resistance proportional to the square of the ball's speed in the previous problem. Let the drag coefficient be cW=0.5, the softball radius be 5 cm and the mass be 200 g. (a) Find the initial speed of the softball needed now to clear the fence. (b) For this speed, find the initial elevation angle that allows the ball to most easily clear the fence. By how much does the ball now vertically clear the fence?
