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.
