Assertion: A man who falls from aheight ...

Assertion: A man who falls from aheight on a cement floor receive more injury than when he falls from the same height on a heap of sand.
Reason: The impulse applied by a cement floor is more than the impulse by sand floor.

A

If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.

B

If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.

C

If Assertion is Trie but the Reason is False.

D

If both Assertion `&` Reason are false

Text Solution

Verified by Experts

    Two balls of same mass are dropped from the same height h , on to the floor. The first ball bounces to a height h / 9 , and the second ball to a height h / 36 after the collision. The impulse applied by the first and the second ball on the floor are I_(1) and I_(2) , respectively. Find (7 I_(1))/(I_(2)) .
