(5%) Problem 17: A bicycle and rider with mass m rolls down a hill at constant velocity under the influence of gravity with negligible rolling resistance. The hill makes an angle of 8 = 19 degrees with respect to the horizontal. The force of air resistance, termed "drag", has a magnitude of Fa= 78 N. Assume that the x-direction is parallel to the slope of the hill and the y-direction is perpendicular to the hill as shown. Randomized Variables 0=19" Fa 78 N
