Question

A mover pushes a box with a force of 31N up the moving van ramp that is at an angle of 33 degrees upward from horizontal. The height of the moving truck is 1.5m. Find the Work done by the mover.

Answer 1

Pussing force F = 31 N

Inclined angle of van ramp = 33º

Height of the moving truck h = 1.5 m

The Work done by the mover W = ?

Distance d = 1.5/sinθ

d = 1.5 / sin33º

d = 2.754 m

W = Fd cosθ

W = 31*2.754*cos33º

W = 71.6 J

The Work done by the mover is 71.6 J
