Homework Help: Riding a motorcycle on inclined plane

  1. Sep 21, 2008 #1
    1. The problem statement, all variables and given/known data

    A motorcycle and a 60.0 kg rider accelerate at 3.0 m/s^2 up a ramp inclined 10 degrees above the horizontal. What is the magnitude of the force on the rider from the motorcycle?

    2. Relevant equations

    F=ma

    3. The attempt at a solution

    I'm not quite sure which forces the motorcycle are exerting on the person. I know the person exerts a downward force on the motorcycle (due to gravity) so it would exert the same force back. Would the direction of this force be vertical or perpendicular to the plane?

    Also, the motorcycle is pushing the person up the ramp so this forward force would be [tex]ma - mg \sin 10^{\circ}[/tex] right?
