A horizontal force of 150 N is used to push a 33.0 kg packing crate a distance of 6.65 m on a rough horizontal surface. If the crate moves at constant speed and the work done is 997.5 joules. What is the coefficient of kinetic between the crate and the surface.

  • Physics - ,

    workin-friction=workdone
    150*6.65- mg*mu*6.65=997.5
    solve for mu.
