Assertion: A quick collision between two bodies is more violent that show collision , even when initial and final velocity are identical.
Reason: The rate of change of momentum determine that force is small or large.

Options

A. If both assertion and reason are true and reason is the true explanation of assertion.
B. If both assertion and reason are reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

A

Explanation

(a) Momentum `p = mv` or `p prop v`. i.e., momentum is directly proportional to its velocity, so the momentum is greater in a quicker collision between two bodies than in slower one. Hence, due to greater momentum quicker collision between two between two bodies will be more violent even initial and final velocities are identical.
