Question

a body of mass 2 kg is thrown vertically upwards with the
initial velocity of 20 m s-1 what will be its potential
energy at the end of 2 seconds (g=10m s-2)

nitish.gupta · Accepted Answer

Potential energy due to gravitational force is given as, P E = mgh

We have, u = 20 m/s, a = â€“10 m/s2, t = 2 s, s = h1

Hence potential energy after 2s, P E 1 = (2 kg) ï¿½ (10m/s2) ï¿½ (20 m) = 400 J
