A person of mass M is equal to 90 kgs standing on a smooth horizontal plane of ice throws a body of mass is equal to 10 kgs horizontally on the same

surface if the distance between the person and body after 10 seconds 10 metres the the kinetic energy of the person in joules is how much


As the person is standing still without motion
so, kinetic energy = 1/2 mv²
m = 90 kg and v = 0 m/s
so, kinetic energy is zero
0 0 0
