Question
The height of a ball at a given time is modelled by the function h(t)=5t^2+7t+1 where h(t) is in metres and time is in seconds . When will the ball hit the ground

I think you must mean
h(t) = -5t^2+7t+1
or the ball will never come down at all!
If so, h=0 when t = (7+√69)/10
h(t) = -5t^2+7t+1
or the ball will never come down at all!
If so, h=0 when t = (7+√69)/10
