Asked by Marina

A projectile is fired straight up from a cliff which is 200 feet above ground with an initial velocity of 220 ft/sec. Assume that the only force affecting the projectile during flight is from gravity which produces a downward acceleration 32 ft/sec^2. Find an equation from the projectile's height above the ground as a function of time t ( if t = 0 when the projectile is fired).

LOL - look above where you called it a Physics question.

The position function would be
s(t)=-32t^2+220t+200
Enjoy! Sorry i replied 4 years late because this the only time i saw a website like this.

It -16t^2 not -32t^2 sorry for the wrong info i was so sleepy that time. :) good luck
