Can someone please help me? =)
The equation below describes the height, h, of the tshirt, 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 tshirt 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 tshirt. Show your work.
What does the equation from #1 tell you about the value of the velocity, v, when t = 0? Explain.

Best ResponseYou've already chosen the best response.0c = initial height = 5 ft h = 16t²+vt + 5 At t = 3 s, h = 131 ft Solve this equation for v 131 = 16(3)² + 3v + 5

Best ResponseYou've already chosen the best response.0I thought it was when t=3.

Best ResponseYou've already chosen the best response.0Would it be v=41 when t=0? Maybe I'm way off.
