m*g = 302kg * 9.8N/kg = 2960 N. = Wt. of
motorcycle.
Fp = 2960*sin24 = 1204 N. = Force parallel to the ramp.
Fa = 235 N. = Force of air resistance.
a = (Fap-Fp-Fa)/m = (2860-1204-235)/302=
4.71 m/s^2
A 302 kg motorcycle is accelerating up along a ramp that is inclined 24° above the
horizontal. The propulsion force pushing the motorcycle up the ramp is 2860 N, and the
air resistance produces a force of 235 N that opposes the motion. Find the magnitude
of the motorcycle’s acceleration.
