well, just plug in your numbers and solve for t when the height is zero:
-16t^2 + 184t = 0
just a good old quadratic equation.
The height of a projectile fired upward is given by the formula
s = v0t − 16t2,
where s is the height, v0 is the initial velocity, and t is the time. Find the time for a projectile to return to Earth if it has an initial velocity of 184 ft/s.
