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 θ = 19 degrees with respect to the horizontal. The force of air resistance, termed "drag", has a magnitude of Fd = 66 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. 1. What is the sum of the forces in the y direction, ΣFy in Newtons? 2. Input an expression for the sum of the forces in the x-direction, ΣFx, in terms of the quantities given and variables available in the palette. 3.Using the information above, what is the total mass of the bike and rider m in kg?
