Question

A ball is thrown from a height of 2 feet with an initial upward velocity of 30

Answer 1

Given the function:

`h(t)=2+30t-16t^2`

If the ball's height is 15 feet:

`\begin{gathered} h(t)=15 \\ \\ \Rightarrow2+30t-16t^2=15 \end{gathered}`

Solving the quadratic equation for t:

Finally, to the nearest hundredth:
