Answer:
Between 2 & 3 seconds. Or we can write it as 2<t<3
Step-by-step explanation:
t = elapsed time in seconds
h(t) = height of the ball at time t
So we just need to replace h(t) with 100 and start to solve. In the end, the answer will be t=2, or t=3 or we can write it as 2<t<3. You can check it by plugging in the number into the equation.
