Question

A.)a 5kg box is pushed along a horizontal frictionless surface by a force of 100N and moves a distance of 10m. Find the work done on the box.
B.)the same box is lifted to a height of 10m by a force of 100N.Find the work done on the box?

Answer 1

Hi.

Here is the answer---

__________________

(a)

Distance = 10 m.
Force = 100 N.

Thus, Work Done = 5 × 100
                             =  500 J

(b)
Distance = 10 m.
Force = 100 N.

Thus, Work Done = 100 × 10
                             = 1000 J.
