A box of books weighing 328N moves with a constant velocity across the floor when it is paged with a force of 385N exerted downward at an angle of 25.3 below the horizontal. Find muK between the box and the floor

  • Physics -

    the force increases the normal downward force.

    Forcehorizontal=frictionforce=ma=0
    385cos25.3=mu(328+385sin25.3)
    solve for mu.
