12. Suppose your catapult launches from the fruit or vegetable with an upward speed of 45 feet per second. That means v0=45.
Rewrite the equation y=-16t^2+v0t+6 with v0=45. Then substitute for t to find the height of your fruit or vegetable 1 second after launch and 2 seconds after launch. Show your work.

13. Use any method you wish to find the vertex of the graph of the quadratic equation you wrote for question 12. Round each coordinate to the nearest tenth. Explain your method.

14. What is the maximum height reached by your fruit or vegetables if it is launched with an initial vertical velocity of 45 feet per second? How do you know? (2 points: 1 point for the maximum height, 1 point for the justification)

15. To reach the desired maximum height for your fruit or vegetable, would the initial vertical velocity have to be greater or less than 45 feet per second?
