A football spends a total of 5 seconds in the air. It reaches a peak height of 20 meters. How long does it take to reach its peak height?
To find out how long it takes for the football to reach its peak height, we need to understand that the time it takes for an object to reach its peak height is half of the total time it spends in the air.
In this case, the total time the football spends in the air is given as 5 seconds. Therefore, to find the time it takes to reach its peak height, we need to divide the total time by 2.
Let's calculate:
Time to reach peak height = Total time / 2
= 5 seconds / 2
= 2.5 seconds
Therefore, it takes the football 2.5 seconds to reach its peak height.
