Knowledge Check

  • 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

  • Statement-1 : A man falling from a given height on hard ground is hurt more than falling on a soft bed from same height. Statement-2 : A man falling from a given height on hard ground experiences larger impulse than falling on a soft bed in coming to rest in both cases.

    A
    Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
    B
    Statement -1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.
    C
    Statement-1 is true, statement-2 is false.

    Why does a child feel more pain when she falls down on a hard cement floor, than when she falls on the soft muddy ground in the garden ?

    A particle of mass m falls from a height h on a mass m and gets stuck to it. Then,

    Two identical balls are dropped from the same height onto a hard surface, the second ball being released exactly when the first ball bollides with the surface. If the first ball has made two more collisions by the time the second one collides. Then the coefficient of restitution between the ball and the surface satisfies :
