Answer:
T = 0.225 s
Explanation:
The speed of a projectile at the highest point of its motion is the horizontal speed of the projectile. Considering the horizontal motion with negligible air resistance, we can use the following formula:

where,
T = Total time of ball in air = ?
R = Horizontal distance covered = 40 m
 = horizontal speed = 9 m/s
 = horizontal speed = 9 m/s
Therefore,

<u>T = 0.225 s</u>
