what
ITS BLANK FOR ME I WISH I COULD HELP YOU
Answer:
1.61 second
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
Answer:
The time it takes the ball to rise equals the time it takes to fall.
Explanation:
because what goes up at some point must come down
