A 4.6-kg block slides down an inclined plane that makes an angle of 26° with the horizontal. Starting from rest, the block slides a distance of 2.6 m in 4.9 s. Find the coefficient of kinetic friction between the block and plane.

  • Physics -

    find the acceleration down the plane
    distance=1/2 a t^2 solve for a.

    Then, summing forces on the plane

    forcedown-friction=ma
    mg*sinTheta-mg*cosTheta*mu=ma

    solve for mu.
