Question 256232
It is simpler dividing through by 16
33 = 14t -t^2 so
t^2 - 14t + 33 = 0*[invoke quadratic "t",-1,14,-33 ]
This gives t = 3 and t = 11. So it will pass 528 feet after three seconds, carry on until it runs out of speed after 7 seconds when it starts to drop until it passes 528 feet on the way down after 11 seconds hits the ground after 14 seconds
