Como parte de una prueba de tiro vertical se lanza una roca, con una antigua catapulta romana, verticalmente hacia arriba con una velocidad inicial de 100m/s

Translated from Spanish language:

"As part of a vertical shooting test a rock is thrown, with an ancient Roman catapult, vertically upwards with an initial speed of 100m / s."

Explanation:

As, the motion can be termed as more of a projectile form, while the initial velocity of the projectile or the body in motion is about a 100m / s. We can easily determine the final velocity, Vf of the body by the following equation given as follows. And, let say that the initial time taken is about 2 seconds. So, we can put the values of the gravity, along with the time, t in the following equation and get a valid result for all of this in a more proper way. Vy = V (x) - gt, ⇒ V (y) = 100 - (9.8) * (2 seconds), V (y) = 80.4 m/sec. "Answer"
