Question 959302: 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 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, v, when t = 0? Explain.

-------------------------
change to
( helps to explain better )
----------------------------
The height is ft when the
cannon is fired at , so
-----------------------------
You are given:
The initial velocity is 90 ft/sec
----------------------------
When
What ever the velocity is at
the height is still ft, so
the velocity can't be determined
from this equation
