The kinetic energy of a light body and a heavy body is same. Which one of the following statements is CORRECT?
Options
- AThe light body has greater momentum.
- BA body having high velocity has greater momentum.
- CBoth bodies have same momentum.
- DThe heavy body has greater momentum.
Correct answer
D. The heavy body has greater momentum.
Step-by-step solution
Kinetic energy, k = 1 2 my ²= ( mv )² 2 ~m = p ² 2 ~m or p = 2 mk i.e., p = m Thus the heavier body has a greater momentum than the lighter one.
