Help with Dynamics

  1. Feb 17, 2009 #1
    1. The problem statement, all variables and given/known data
    A flat-bed truck with a frictionless ramp accelerates forward.

    /l (That 35 is the angle, and a 5kg block rests on the hypotenuse)
    --- / l
    - - /35 l
    - ---------------

    The acceleration of the truck is suck that a 5.0kg block is stationary (relative to the ramp). If the rolling coefficient of friction is (mew=0.10) Find the force the engine is exerting on the 12000kg truck.

    2. Relevant equations
    F=ma, Ffriction=Fnormal*mew

    3. The attempt at a solution
    I found the block accelerates 9.8m/s^2 downwards and 13.98m/s^2 to the left, ant the total acceration is 17.1m/s^2

    I found the force of friction on the truck (12000*9.8*0.1) to be 11760Netwons.
