Question

If the body of mass 2 kg is raised vertically upward to the height of the 2m what will be the work done?

Answer 1

Answer:

39.2N

Explanation:

Energy stored in the body is only due to change in potential energy.

So here,

E = m * g * (H2 - H1) (P.E = mgh)

putting g = 9.8 m/s^2

H2 = 2 m (final height)

H1 = 0 (Initial height)

m = 2 kg

E = 2 * 9.8 * (2 - 0)

= 39.2 N
