How do you determine the total time of flight for a projectile?

To find the total time of flight for a projectile, you can multiply the time taken to reach the peak height by two. This is because a projectile's motion is symmetrical in the absence of air resistance.

When a projectile is launched, it ascends to a peak height where its vertical velocity becomes zero before it starts descending back to its original launch height. The time taken to ascend to the peak is equal to the time taken to descend back down. Therefore, the total time of flight is simply the time to reach the highest point multiplied by two.

This method works well for uniformly accelerated motion, like that of projectiles under the influence of gravity. It's important to note that this applies only when the projectile is launched and lands at the same vertical height. In cases where the launch and landing heights differ, other calculations must be employed to determine the total time of flight.
