Question

a lighter object A and a heavier object B are initially at rest.both are imparted the same linear momentum. which will start with greater kinetic energy? give reason.​

Answer 1

$\huge\fcolorbox {magenta} {red} {Answer}$

1. Let m1 and m2 be the masses of light object A and heavy objects B and v1 and v2 be their respective velocities

2. since both are imparted with same linear momentum,

m1v1 = m2v2

3. As m1<m2 the lighter body A has more kinetic energy
