Hi  

The height of a projectile fired upward is given by the formula: 

s = v0t − 16t^2    |Note the use of " ^ "

Find the time for a projectile to return to Earth if it has an initial velocity of 248 ft/s.

s = 0 when the projectile returns to earth.

0 = 248t - 16t^2

16t^2 = 248t

t = 248/16 = 15.5s

Wish You the Best in your Studies.
