question
a tennis ball is dropped from a certain height. the graph below shows its height h in centimeters after t seconds. what is the ball’s initial height?

(graph with points (0, 313.6) and (0.8, 0), axes labeled time (in seconds) and height (in centimeters))

answer attempt 1 out of 2

Explanation:

Step1: Understand Initial Height

The initial height of the ball is the height at time \( t = 0 \) seconds. On the graph, the point corresponding to \( t = 0 \) is the y - intercept.

Step2: Identify the Point at \( t = 0 \)

From the graph, we can see that when \( t = 0 \), the point is \( (0, 313.6) \). The y - coordinate of this point represents the height of the ball (in centimeters) at \( t = 0 \) seconds.

Answer:

The ball's initial height is 313.6 centimeters.
