A light mass  and heavy mass have equal momentum. Which will have more kinetic energy?
Asked by chatterjee.chaitalichat | 08 Apr, 2019, 08:27: PM
answered-by-expert Expert Answer
Kinetic energy K = (1/2)mv2   = [ 1/(2m) ] (mv)2 = p2 /(2m)  ...................(1)
 
where p = mv = mass×velocity = momentum
 
Both the mass has equal momentum. Hence as per eqn.(1), lighter mass has more kinetic energy
