The number of second it takes the rocket to reach its maximum height is 3.194 seconds.
What is maximum height ?
The maximum height attained by any body is the height at which the body completes its ascent and then at that time interval starts to descend down.
The time taken by the body to reach the maximum height is given by -
t = √(2h/g)
Where t is the time taken, h is the maximum height and g is the acceleration due to gravity.
How to calculate the time taken by the rocket to reach maximum height ?
From the graph, it is seen that the body attains a maximum height of 50m as from that point, the rocket starts to descend downwards.
Thus by using the above formula,
⇒ t = √(2*50/9.8) seconds
∴ t = 3.194 seconds.
Also we can check from the graph, the time taken by the rocket to reach the maximum height of 50m is near to 3.12 seconds.
Therefore, the number of second it takes the rocket to reach its maximum height is 3.194 seconds.
