Question

A toy car rolls down an incline at a constant velocity. The car's mass is m = 1.1 kg and the ramp makes an angle of \theta = 17 degrees with respect to the horizontal. Assume the rolling resistance is negligible. - Part (a) ✔ What is the magnitude of the car's acceleration, a in m/s2? a = 0.000 ✔ Correct! - Part (b) ✔ What is the numeric value for the sum of the forces in the x-direction, \Sigma Fx, in Newtons? \Sigma Fx = 0.000 ✔ Correct! Part (c) Assuming the car experiences only air resistance in opposition to its motion, with magnitude Fr. Write an expression for the sum of the forces in the x-direction using the acceleration due to gravity, g, and the variables provided
