A mover is pushing a 148kg box up a ramp. The ramp is inclined at an angle of 30.4 degrees. Since the box is on wheels, assume that friction is negligable. Calculate the force the mover exerts to push the box up the ramp at a constant rate of 1.26 m/s. Assume he pushes parallel to the ramp.
A block of mass mį = 4.00 kg is put on top of a block of mass mp = 7.00 kg.
