Since no one answered the first time, I'll try again...
The equation for a projectile's height versus time is h(t)=-16t^2+v0t+h0. A ball is thrown vertically upward with an initial velocity of 5 ft/sec from a height of 2 ft. Which function models its motion.
A. y= -16t^2-5t-2
B. y=- 16t^2+2t+5
C. y= -16t^2+5t+2
D. y= 16t^2-2t-5
