A clerk moves a box of cans down an aisle by pulling on a strap attached to the box. The clerk pulls with a force of 188.0 N at an angle of 26° with the horizontal. The box has a mass of 30 kg, and the coefficient of kinetic friction between the box and the floor is 0.45. Find the acceleration of the box.
in m/s2 down the aisle

    remember the horizontal component of his pulling is the pulling force
    hte upward component of his pulling just reduces the normal force, thence reduces friction.

    net force=ma
    horizontal force-mu*normalforce=ma
    solve for a.
