Two balls are dropped from a height of 6 m. Ball A bounces back up to a height of 4m whereas ball B bounces back up to 2m. Which ball experiences the larger impulse during its collision with the floor?
(a) ball A (b) ball B (c) both experiences the same impulse. (d) its impossible to tell without knowing the masses of the balls.

$$I=\Delta p$$where Delta p is the change in momentum given by$$mv_2-mv_1$$

anonymous · Answer

it is ball a

turingtest · Answer

I don't see how you can get the answer without the masses.

anonymous · Answer

yes exactly turingtest 
and john4m2 why is it ball A?

anonymous · Answer

yeah it`s true but you can determine through their heghts after bouncing and determine the greater mass and it`s impossible to solve for the impulse

anonymous · Answer

the question asks about the impulse, is it possible to compare the two impulses without the masses?

anonymous · Answer

yeah actually

anonymous · Answer

alright, so its option (d) then?

anonymous · Answer

sure

anonymous · Answer

Impulse is the change of momentum by definition and so Option d may be correct but if we consider the balls having same mass then they experience same impulse
