The parasailing system shown uses a winch to pull the rider in towards the boat, which is travelling with a constant velocity. During the interval when ( is between 20º and 40º, (where t = 0 at ( = 20º) the angle increases at the constant rate of 2 º/s. During this time, the length of the rope is defined by the relationship r = 125 - 1/3 t3/2, where r and t are expressed in meters and seconds, respectively. At the instant when the rope makes a 30 degree angle with the water, the tension in the rope is 18 kN. At this instant, what is the magnitude and direction of the force of the parasail on the 75 kg parasailor?
