Some parasailing systems use a winch to pull the rider back to the boat. During the interval when q is between 20 and 40 degrees, the length of the rope follows the relationship r = 200 - t^(3/2) (where q = 20 degrees at t=0) and the angle increases at the constant rate of 2 degrees/sec. If the boat is travelling at a constant rate of 20 knots, (a) plot the magnitude of the velocity of the parasailer as a function of q, (b) determine the total acceleration of the parasailer at t= 5 sec.
