Question

two bodies of mass m1 nd m2 where m1 is greater than m2 having same momentum,which one have greater kinetic energy

Answer 1

m2 has greater KINETIC ENERGY as it's velocity will be more than that of m1.

Answer 2

Relation between linear momentum and kinetic energy is:

$ke \: = p {}^{2} \div 2m$
So, KE is inversely proportional to root m
hence,
k1 / k2 = m2/m1
Therefore, M2 has higher KE.
