miguel throws a ball up in the air. the graph below shows the height of the ball h in meters after t seconds. how long is the ball in the air?
Answer
Explanation:
Step1: Identify relevant points
The ball is in the air from when $t = 0$ until it hits the ground again. The ball hits the ground when $h=0$. From the graph, the points are $(0,0)$ and $(3,0)$.
Step2: Calculate time - interval
The time the ball is in the air is the difference in $t$ - values of the start and end points. The start time $t_1 = 0$ and the end time $t_2=3$. The time in the air $T=t_2 - t_1$. $T=3 - 0=3$
Answer:
3 seconds
