Question

a man of mass 2 kg jump from height of 0.5 m is equal to 10 metre per second square , what will be his energy at the highest point

Answer 1

energy is mass×acceleration×height
=2×0.5×10
=10joules

it is potential energy.

Answer 2

Given,
mass = 2kg
height achieved = 0.5m
accleration = 10 m/s^2

The energy at it's highest point will be it's potential energy given by,

Energy= mass*accleration*height
=} 2*0.5*10
=}10 joules
so,
Energy at it's highest point will be 10 joules.
