Explanation:
Angle of projection, θ = 53°
maximum height, H = 7.8 m
Let T be the time taken by the ball to travel into air. It is called time of flight.
Let u be the velocity of projection.
The formula for maximum height is given by
By substituting the values, we get
u = 9.88 m/s
Use the formula for time of flight
T = 1.61 second
