Con qué velocidad inicial debe lanzarse un objeto directamente hacia arriba para que su altura máxima sea 25 m?

v₀ = 22.1 m / s

Explanation:

This is an exercise in kinetics, let's set a vertical reference system with the positive direction up.

          v² = v₀² - 2 g (y-y₀)

the final velocity at the highest point is zero and as it leaves the floor the initial height is zero

          0 = v₀² - 2gy

         v₀ =

let's calculate

        v₀ =

        v₀ = 22.1 m / s

i dont have a visual in front of me, but i can you reason to try to get the right one. the graph should look like this, 0 to 6 there is a spike, 12 to 14 there should be a very low point. slight increase in the graph at 12 to 14, and flat 14 to 18
