An object is dropped from a vertical distance of 25.5 m above the ground, and it takes 2.28 sec to fall that distance. a second identical object to launched from the same height, with a horizontal velocity of 45.9 m/s. how long does the second object take to fall the 25.5 m?

The second object takes 2.28 s to fall the 25.5 m.

Explanation:

In this case, both objects take the same time to fall, since no vertical velocity is added to any of them.

You can also confirm this by sepparating the second's object movement into its two directions: in the horizontal one, we have linear uniform motion, and in the vertical one, we have free fall, with exactly the same characteristics as for the first object.
