Need ! 30 ! (also explain )
a ball was thrown with an initial upward velocity of 80 feet per second from an initial height of 4 feet. write an equation for h, the height of the ball in feet, t seconds after it was thrown.

80x^ + 4t + t

Yah I think that’s the answer

S=ut +0.5gt^2

s+4=80t -.5*9.81t^2

I believe

Using the equation of motion, you add 4 because it’s already at a height of 4, it’s negative gravity because it’s going against gravity.

S=80t-0.5gt^2 -4 final answer

the answer is 31.27mph

answer: idk
