Assertion : A quick collision between two bodies is more violent … - Vidyadip

MCQ

$Assertion$ : A quick collision between two bodies is more violent than a slow collision; even when the initial and final velocities are identical.
$Reason$ : The momentum is greater in first case.

✓
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: A.

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

a
In a quick collision, time t is small. As $F \times t =$ constant, therfore, force involved is large. I.e., collision is more violent in comparison to slow collision . Momentum, $p = mv$ or $\therefore p \propto v$ momentum is directly proportional to its velocity, so the momentum is greater in a quicker collision
