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 <u>to return to Earth</u> 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.
