Assertion: A quick collision between two bodies is more violent...

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

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

As Δp=mΔv,Δp∝Δv\Delta p=m \Delta v, \Delta p \propto \Delta v, and F=ΔpΔtF=\frac{\Delta p}{\Delta t} the rate of change of momentum is greater in a quicker collision between two bodies. The quicker collision between two bodies is more violent due to greater force.
