Question

Problem 3: A toy car rolls down a ramp at a constant velocity. The car's mass is m J 1.8 kg and the ramp makes an angle of 6 J 11 degrees with respect to the horizontal. Assume the rolling resistance is negligible constant Otheexpertta.com 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 Expression Select from the variables below to write your expression. Note that all variables may not be required. (a) cos(p), cos(e) in in (p), sin(e), a, B, 0. d, Fr. g, h, m, t (a)

Explanation / Answer

here,

mass of car , m = 1.8 kg

theta = 11 degree

C)

the magnitude of air resistance force is Fr

the sum of forces in x direction => m * g * sin(theta) - Fr
