Question

a man of mass 5 kg jumps from a height of 0.5 m if g is equal to 10 M per second square what will be the his energy at the highest point

Answer 1

Energy at highest point=Gravitational potential energy=Mass × Acc. × Height
= 25. joules!

Answer 2

Given,
mass=5 Kg
height gain=0.5 m
g=10 m/s
Energy = work done
Here, work done = potential energy
And,
potential energy = mgh
=} 5 * 0.5 * 10
=} 25 joules
