A box slides down a 36° ramp with an acceleration of 1.05 m/s2. Determine the coefficient of kinetic friction between the box and the ramp.

  • Physics -

    First write Newton's equation of motion for the direction down the ramp.
    Fnet = Weight*sin 36 - Ffriction = M a

    M g sin36 - M g cos36 *Uk = M a

    Cancel the M's and solve for the kinetic friction coefficient Uk.

    For further help from me, show your work.

  • Physics -

    using this formula i got 8.42, which is not the right answer
