if an object is projected upward with an initial velocity of 80 ft per second, what is t at maximum height

The time at maximum height is 2.49 s.

Explanation:

The time (t) at the maximum height can be found using the following equation:

Where:

: is the final velocity = 0 (at the maximum height)

: is the initial velocity = 80 ft/s

g: is the gravity = 9.81 m/s²

Hence, the time is:

Therefore, the time at maximum height is 2.49 s.
