1020 Solutions Manual
A ball is dropped from rest from a height
h0D1:5
m. The impact between the ball
and the floor has a COR
eD0:92
. Find the formula that allows you to compute the
rebound height
hi
of the
i
th rebound. Furthermore, find the formula that provides
the total time required to complete
i
rebounds. Finally, compute the time
tstop
that the ball will take to stop bouncing. Hint: A formula you may find useful
in the solution of this problem is that of the limit value of a geometric series:
PN1
iD0eiD.eN1/=.e 1/, with jej<1.
