A 10kg trunk lies on a horizontal rough floor,the coefficient of friction between the trunk and the floor is 0.75. Calculate magnitude of force P which is necessary to pull the trunk horizontally if the P is applied horizontally and at 30 degrees above the horizontal.

  • mec 112 - ,

    upward force=Psin30
    horizontal force=Pcos30

    forcefriction=normalforce*mu
    = mu(mg-Psin30)

    horizontal force=friction solve for P
