Using the Workdone relation, the work done by tensional force is 9.35 J and the work done by gravity is 134.75 J

Given the Parameters :

  • mass of the box, m = 25 kg
  • distance traveled, d = 55 cm = 0.55 m
  • Tension on the rope, T = 17 N

Recall the Workdone relation :

W = Force × Distance

W = 17 x 0.55

W = 9.35 J

Work done by gravity can be calculated thus ;

W = mgh

W = (25 x 9.8) x 0.55

W = 134.75 J

Therefore, the work done by tensional force is 9.35 J and the gravity is 134.75 J
