As you guys might know I don't want an answer, I would just like some guidance.
An object is projected upward from the ground with an initial velocity of 128 feet per second. The height s at the end of t seconds is s = .
When does it reach its maximum height and what is it?
The object reaches maximum height when the velocity is 0.
t = 4
s = 128(4)-32(4) = 256 ft
When does it hit the ground and with what velocity?
The object will hit the ground when the height is 0
I got stuck here
