Question

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.

Answer 1

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...
