Question 935194
I'll do the first one to get you started


# 1


Initial Height = 200 cm


It falls to the ground, then bounces up to a height of (4/5)*200 = 160 cm. This is  after bounce 1.


It falls back down, and then rebounds to (4/5)*(160) = 128 cm. This is after bounce 2.


Finally, for bounce 3, it rebounds to a height of (4/5)*(128) = 102.4 cm.



Short summary:


Initial Height: 200 cm
Height after bounce 1: 160 cm
Height after bounce 2: 128 cm
Height after bounce 3: 102.4 cm


Question: "What height will the ball bounce to on the third rebound? "
Answer: <font color="red">102.4 cm</font>
