If momentum of a body is increased by 100% the percentage increase in kinetic energy is:
(a)100%
(b)200%
(c)300%
(d)400%
please write the whole solution also.

Actually it depends upon the velocity of the body....as K.E. =1/2 ×m× v×v
If momentum will increase then velocity will also increase.....it will depend upon velocity as we are taking square of velocity
If momentum will increase then velocity will also increase.....it will depend upon velocity as we are taking square of velocity

T=p22mT=p22m
Therefore if you have p↦2pp↦2p, then:
T↦(2p)22m=4p22m=4TT↦(2p)22m=4p22m=4T
Therefore the kinetic energy quadruples when you double the momentum.
