Question

1. kadir tosses a water balloon upward with an initial velocity of 7 meters per second from a height of 11 meters above the ground. function h models the height of the balloon in meters as a function of time t in seconds. the graph of h is shown. height of a water balloon calculate the approximate average velocity of the balloon to the nearest integer over the interval from 1 second to 2 seconds. ______ meters per second

Explanation:

Step1: Identify heights at t=1, t=2

From the graph: $h(1)=13$ meters, $h(2)=7$ meters

Step2: Apply average velocity formula

Average velocity = $\frac{\text{Change in height}}{\text{Change in time}} = \frac{h(2)-h(1)}{2-1}$
<Expression>
$\frac{7 - 13}{2 - 1} = \frac{-6}{1} = -6$

Answer:

-6 meters per second
