Question

A body of mass 50kg has a momentum of 3000kgms-2 calculate the kinetic energy of a body

Answer 1

As, P = mv..
v = p/m..
= 3000 /50..
So, 60 is the ans..

Answer 2

Answer:

9000J

Explanation:

Here..

mass(m) = 50kg

momentum(p) = 3000kgm/s

We know

Kinetic energy = p*2/2m

=(3000)*2/2×50

=9000000/1000

=90000J
