Question 1199568
First of all, you are solving for the height of the ball, not the time.
Secondly, you are mixing English units and metric units. We are given the speed
and height in m/s and m, but in the formula h(t) = h0 + v0*t - 1/2g*t^2, you are
using g = 32 ft/s^2 instead of g = 9.8 m/s^2. Make the substitution and you will
get a sensible answer for the height.
