Answer:

A body of mass 50kg will have more kinetic energy than another body of mass100 kg have equal momentum.

Explanation:

Given : The mass of two different bodies are 50kg and 100kg respectively.

To Find ;Which body will have more kinetic energy.

Solution:

K.E for the body having 50 kg mass ⇒K.E=1/2mv^2

                                                                     =1/2m*m^2v^2

                                                                    =1/2*50*P^2

P= momentum which is fix for two different bodies.

K.E for the body having 100kg mass⇒ K.E= 1/2mv^2

                                                                      1/2*m*m^2v^2

                                                                       =1/2*100 *P^2

As, 1/100P^2 >1/200P^2  

So, A body having 50 kg have more kinetic energy.
