Let from the height at which ball was thrown = h units
It is given that , ball rebounds the same percentage on each bounce.
Let it rebounds by k % after each bounce.
Height that ball attains after thrown from height h(on 1 st bounce)=
Height that ball attains after thrown from height h (on 2 n d bounce)=
Similarly, the pattern will form geometric sequence.
S=
So, Common Ratio =
Common Ratio= 1 + the percentage by which ball rebounds after each bounce
the percentage by which ball rebounds after each bounce= negative integer= k is negative integer.
