8 5 28
2 3 11.20
-16t^2+16t+192= 0 (when the ball hits the ground, h will be zero)
Use the quadratic formula to solve the equation (If you don't know how to solve quadratic equations, just ping me dude and I'll try my best to help you)
We get x=-3 and 4
Now since time can't be negative, therefore the answer is after 4 seconds
