2. A stone is thrown vertically upward with a speed of 22m/s.
Eduardwww [97]

Answer:

Explanation:

Energy E is conserved:

E=\frac{1}{2}mv^2+mgh

If v₀ = 22m/s, h₀=0m and h₁=25m:

E=\frac{1}{2}mv_0^2=\frac{1}{2}mv_1^2+mgh_1

Solving for v₁:

v_1=\sqrt{v_0^2-2gh_1}

There is no real solution, because the stone never reaches 25m.
