a 10kg block is allowed to slide down a ramp with Mk=0.15. what is the acceleration of the block?

  • slope of ramp? -

    I do not know what Mk is
    Need slope of ramp and friction coefficient.

  • physics -

    By the way, the mass should not matter.

  • physics -

    The numerical value of acceleration, a, will depend upon the angle of the block. Call that angle "A".
    Acclerating force = M g sin A
    Friction force = M g cos * Mk

    Mg(sin A - Mk cos A) = M a

    a = g(sinA - Mk*cosA)
