Question 1028027: 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, h, of the t-shirt, t seconds after it is shot from the cannon c feet above the ground, at an initial velocity of v.
h = -16t^2 + vt + c
Solve the equation for initial velocity, v.
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 the equation from #1 to find the initial velocity of the t-shirt.
What does the equation from #1 tell you about the value of the velocity, v, when t = 0?

Solve for :
----------------------
The initial height is when
given:
ft
sec
------------------
ft/sec
-------------------
When , then because
you are at the initial height
and
That means you cannot determine the initial
velocity at
