At a basketball game, members of the Spirit Club use a t-shirt cannon to launch team t-shirts to spectators in the stands. The equation below describes the height of the t-shirt seconds after it is shot from the cannon feet above the ground, at an initial velocity of . Solve the equation for the initial velocity .
The cannon launched a t-shirt from an initial height of 5 feet. After 3 seconds the shirt has reached a height of 131 feet. Use your equation from #1 to find the initial velocity of the t-shirt. Show your work.
What does the equation from #1 tell you about the value of the velocity when ? Explain.
