Question

billy drops a ball from a height of 1 m. the ball bounces back to a height of 0.8 m, then bounces again to a height of 0.5 m, and bounces once more to a height of 0.2 m. up is the positive direction. what is the total distance of the ball?
if you answer is not an integer, round it to the nearest tenths place (1st decimal place).
______ m

Explanation:

Step1: Count initial drop distance

$1\ \text{m}$

Step2: Sum upward bounce distances

$0.8 + 0.5 + 0.2 = 1.5\ \text{m}$

Step3: Sum downward bounce distances

$0.8 + 0.5 + 0.2 = 1.5\ \text{m}$

Step4: Calculate total distance

$1 + 1.5 + 1.5 = 4.0\ \text{m}$

Answer:

$4.0$
