a tennis ball is dropped from a certain height. the graph below shows its height h in centimeters after t seconds. how long is the ball in the air?
Answer
Explanation:
Step1: Identify key - points on the graph
The ball is in the air from the time it is dropped ($t = 0$) until it hits the ground. The height of the ball is $h = 0$ when it hits the ground.
Step2: Read the time value
From the graph, when $h = 0$, the value of $t$ is $0.6$ seconds.
Answer:
$0.6$ seconds
