if two identical balls are dropped from the same height, the ball which experiences the greatest impulse when it strikes the floor will bounce the highest. true or false.

Question

souvik · Answer

impulse = change in momentum
impulse=m{v-(-u)}   [m=mass, v=velocity of the ball after collision and u=velocity of the ball before collision] 
v and u are in opposite direction
$$v=-u+\frac{ impulse }{ m }$$ 
m is same for both balls as they are identical.
as they were dropped from the same height...u is same...
