#### Storyboard Text

• No, plus we have our baseball game in a couple days so we need to keep practicing our throws.﻿
• Do you have any ideas for our science fair project for Mr. Johnson's class?﻿
• Yeah, that's a great idea! We should create an equation to represent the situation.﻿
• That's it! Lets do our project on the motion of the ball. We can throw it from an initial height of 6 feet at the velocity of 20 feet per second. Then we will measure the greatest height the ball reaches and how long it takes for it to reach the ground.﻿
• So when you plug in the values the equation would become s(t)=-16t^2 + 20t + 6. Cool, lets go measure the maximum height it reaches and how long it takes to reach the ground. ﻿
• The equation would be s(t)=-16t^2 + V(t) + S. We just need to plug in the values.
