How long to reach the ground from the maximum height
First, calculate the time of flight (T)
The time taken (t) from maximum height to the ground is:
So, we have:
Another representation is:
At ymax, the time is: t1
On the ground, the time is t2
The difference between these times is the time taken.
So;
Since air resistance is to be ignored, then
--- i.e. time to reach the maximum height from the ground equals time to reach the ground from the maximum height
