Explanation:
To find the time above and below ymax/2 we use the following kinematic formula
Where
= Final Velocity
= Initial Velocity
= Gravity
= Time
Notice that we need to first find the values of velocity to solve this equation. To do that we use the following kinematic formula
Where
= Final Velocity
= Initial Velocity
= Gravity
= Height
Taking h = ymax/2 we get the following formula
To find the value of value of ymax in terms of v0 we use the law of conversation of energy
Now we can substitute the value of ymax
Now using the original equation to find time, we input the value of V1 and find time in terms of V0
Assuming final velocity v is 0 (since at the top velocity is zero)
This gives us total time from bottom to top
To find time from ymax/2 to top we substitute the value of V1
The time he is above ymax/2 is nothing more than the difference between t and t1
To find the required ratio we divide t1 by (t - t1)
