Question 10. The total flight requires a time that is? (a) four times the time necessary to reach the maximum height. (b) thrice the time necessary to reach the maximum height (c) equal to the time necessary to reach the maximum height. (d) twice the time necessary to reach the maximum height Answer
The time of flight is just double the maximum-height time... t = 2 * V₀ * sin(α) / g Let's have a look at the final time of flight equation again: the higher the value of a sine is, the longer the time in the air. The maximum value of sine occurs when angle = 90°. So if you throw an object upwards, it will keep moving for the longest time.
