Answer
a) about $140\text{ cm}$
b) about $250\text{ cm}$
Work Step by Step
a) Using the line graph below, then the bounce height of the ball when it is dropped from $175\text{ cm}$ is about $140\text{ cm}$.
b) In centimeters, $2\text{ m}$ is equivalent to $200\text{ cm}$. Based on the graph below, the drop height should be about $250\text{ cm}$ so that the initial bounce height is about $200\text{ cm}$ or $2\text{ m}$.
