If you drop a ball a height of 5.2 metres and it bounces back to 3/4 of its height after each bounce, then you drop another ball from a height of 4.5 metres and it bounces back to 80% of its height after each bounce.
Which ball is the highest on the second bounce?

5.2*(3/4)^2 = 2.925
4.5 *(.8)^2 = 2.88

the 1st

the first ball

first ball

first bounce- 5.2 times 3/4 is 3.9

second bounce- 3.9 times 3/4 is 2.925

second ball

first bounce- 4.5 times 80% is 3.6

second bounce- 3.6 times 80% is 2.88

2.925>2.88

5.2*3/4*3/4=2.925 metres.

4.5*0.8*0.8=2.88 metres
the first ball is the highest at second bounce.
