Question

A body of mass 0.5 kg travels in a straight line with velocity where. What is the work done by the net force during its displacement from x = 0 to x = 2 m?

Open in App

Solution

Mass of the body, m = 0.5 kg

Velocity of the body is governed by the equation,

Initial velocity, u (at x = 0) = 0

Final velocity v (at x = 2 m)

Work done, W = Change in kinetic energy
