292 kg motorcycle is accelerating up a ramp that is 30 degrees above the horizontal.

Propulsion force pushing the motorcycle up ramp is 3150 N. Air resistance produces a force of 250 N that opposes the motion.

Find that motorcycle's acceleration.

  • Physics -

    Resolve all forces in the direction of the ramp, up=positive.
    Propulsion force, P= +3150N
    Resistance, A = -250N
    due to weight of motocycle, W = -mgsinθ
    Net force, F = P+A+W
    Use F=ma to solve for a.
