Question

. kinetic energy of a lighter body and heavier body are equal.which have greater momentum?<br /><br /><br /> can I solve this by the following method?if not ,why?<br /><br /><br /><br /><br />

Answer 1

The body with heavier mass will have the greater momentum for eg let the body be 4 kg and 2 kg having velocity 2 m/s and 2.81 m/s
I choose this as the first condition states that they should have same kinetic energy solving this you will get the value as having same kinetic energy
But for momentum it would be one having largest mass here 4*2 = 8
Smallest mass here 2*2.81 = 5.7 something this explains the actual scene
