What is its time interval between the release of the ball and the time it reaches its maximum height? Its initial vertical speed is 9.5 m/s and the acceleration of gravity is 9.8 m/s2. Neglect air resistance.

0.93 seconds is the time interval between the release of the ball and the time it reaches its maximum height.

Explanation:

Given that,

Initial speed of the ball, u = 9.5 m/s

When it reaches to the maximum height, final speed of the ball, v = 0

It is required to find the time interval between the release of the ball and the time it reaches its maximum height. Using third equation of motion to find the maximum height reached.

Now using second equation of motion to find the time interval between the release of the ball and the time it reaches its maximum height as :

So, 0.93 seconds is the time interval between the release of the ball and the time it reaches its maximum height.

i. like it i'm gonna edit it tomorrow

im sorry i dont know
