A body of mass 2kg is thrown vertically upwards

Asked by admin @ 16/08/2021 in Physics viewed by 318 People

A body of mass 2 kg is thrown vertically upwards with an initial velocity of 20m/s. What will be its potential energy at the end of 2s ? ( Assume g = 10 m/s^2).

Answered by admin @ 16/08/2021

H=vt+1/2at^2
h=20×2 + 1/2 × (-10)2×2
h= 40 + -(20)
h=20 m

potential energy
U=mgh
U=2 × 10 × 20
U=400J
