a 30-n box is pulled upward 6.0 m along the surface of a ramp that rises at 37° above the horizontal. how much work does gravity do on the box during this process?

Answer :

ONYEBUCHINNAJIGO

The work done by the gravity on the box is 108.2 J.

The given parameters;

  • weight of the box, W = 30 N
  • distance traveled by the box, h = 6 m
  • angle of inclination of the box, Ф =  37°

The work done by the gravity on the box is the product of the upward force experienced by the box and the height the object was raised.

The work done by the gravity on the box is calculated as;

W = F x h

W = Wsin(θ) x h

W = 30sin(37°) x 6

W = 108.2 J

Thus, the work done by the gravity on the box is 108.2 J.
