Q- Calculate the kinetic energy of the body of mass 0.1 kg and momentum 20 kg ms-1.

A- Given -:

mass of the body = 0.1 kg

momentum of the body = 20 kg ms-1

We know that,

p = √2mK

20 = √2*0.1*K

In squaring both the sides we get,

400 = 2/10 K

400*10/2 = K

2000 J = K
K = 2000 J

Hence the Kinetic Energy of the body is 2000 J.
