MATHS - For $0.2

Branch to enter.

A ball bounces 2m on its first bounce, then 1.5m on the second bounce. Every bounce it loses 25% of its previous height.

What is the total distance the ball will eventually travel?

Assume the ball was launched vertically from the ground originally. Hence 2m up followed by 2m down, etc.

can we have a hint. How many times does the ball bounce?

Hint: "limiting sums"

8m

Technically 16m as the ball goes up and then down. Need to double it

I'll give you half marks.
