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
1.Solve the equation for initial velocity, v.
2.What does the equation from #1 tell you about the value of the velocity, v, when t = 0? Explain.

The answer for the first question is something like $$v=-\frac{ -16t ^{2}+c-h }{ t }$$Right?

ellie202000 · Answer

Is the answer v=0 because t=0 which means the ball hasn't started to move?
