Question

A small ball of mass m
is aligned above a larger ball of
mass M
= 0.63 kg (with a slight separation,
as with the baseball and basketball, and the two are dropped simultaneously from a height of h
=1.8 m. (Assume the radius
of each ball is negligible relative
to h.) (a) If the larger ball rebounds
elastically from the floor and then
the small ball rebounds elastically
from the larger ball, what value of m
results in the larger ball stopping
when it collides with the small ball?
(b) What height does the small ball
then reach
