(3%} Problem 9: A bicycle and rider with mass m rolls down a hill at constant velocity under the inuence of gravity with negligible rolling resistance. The hill makes an angle of 8 = 18 degrees with respect In the horizontal. The force of airresistanoe, termed "drag", has a magnitude off}: 65 N. J' Assume that the iii-direction is parallel to the slope of the hill and the y-direcon is perpendicular to the hill as shown. Randomized Variables 6:18\" =N -' *33% Part (c) Using the information above, what is the total mass of the bike and rider m in kg
