Some parasailing systems use a winch to pull the rider back to the boat. During the interval when is between 20° and 40° (where t = 0 at 0 = 20°), the angle increases at the constant rate of 2°/s. During this time, the length of the rope is defined by the relation- ship r = 600-5/2, where r and t are expressed in feet and seconds, respectively. Knowing that the boat is traveling at a constant rate of 15 knots (where 1 knot = 1.15 mi/h), (a) plot the magnitude of the velocity of the parasailer as a function of time, (b) determine the mag- nitude of the acceleration of the parasailer when t = 5 s.
