aaliyah throws a ball up in the air. the graph below shows the height of the ball h in meters after t seconds. how many seconds have gone by when the ball is at its highest point?
Answer
Explanation:
Step1: Identify the highest - point on the graph
The highest point of the graph of height $h$ vs time $t$ is the vertex of the parabolic - shaped curve. The coordinates of the vertex are given as $(1,4.9)$.
Step2: Determine the time value
The $x$ - coordinate of the vertex represents the time $t$ when the ball is at its highest point. In the coordinate $(1,4.9)$, the $x$ - coordinate is $1$.
Answer:
$1$
