The value is
Explanation:
From the we are told that
The initial speed of the object is
The greatest height it reached is
Generally from kinematic equation we have that
At maximum height v = 0 m/s
So
=>
Here H is the height from the initial height to the maximum height
So the initial height is mathematically represented as
=>
=>
Generally the time taken for the object to reach maximum height is mathematically evaluated using kinematic equation as follows
At maximum height v = 0 m/s
=>
Generally the time taken for the object to move from the maximum height to the ground is mathematically using kinematic equation as follows
Here the initial velocity is 0 m/s given that its the velocity at maximum height
Also g is positive because we are moving in the direction of gravity
So
=>
Generally the total time taken is mathematically represented as
=>
=>
