Question

a ball is dropped from a height of 144 m and it rebounds to two thirds of the height from which it falls. if it continues to rebound, what distance will the ball have travelled before coming to rest?

Answer 1

Distance traveled first time+2×{a÷(1-r)}

Where a=96 and r=2/3  

=144+2{96÷(1–2/3)}

=144+2{96÷(1/3)}  

=144+2{96×3}

=144+2×288

=144+576

=720

So the final answer for this question is 720.
