You can put this solution on YOUR website!
S(t) = -16t^2 + 150t + 5
using the quadratic equatio:x = (-b +- sqrt( b^2-4*a*c ))/(2*a)
t=(-150+-sqrt[150^2-4*-16*5])/2*-16
t=(-150+-sqrt[22,500+320])/-32
t=(-150+-sqrt22,820)/-32
t=(-150+-151.063)/-32
t=(-150+151.063)/-32
t=1.063/-32
t=-.033 answer.
t=(-150-151.063)/-32
t=-302.063/-32
t=9.4 answer.
