The body moves up at the initial speed of 20 m / s. Determine what maximum height it comes.

These tasks: V0 (the initial speed of the given body when moving up) = 20 m / s.

Reference values: G (acceleration of free fall) ≈ 10 m / s2.

1 solution method) Energy conservation: EP = M * G * H = EK = M * V0 ^ 2/2, from where H V0 ^ 2 / 2G = 20 ^ 2 / (2 * 10) = 400/20 = 20 m.

2 solution method) formula for calculating the path traveled: S = H = (V ^ 2 – V0 ^ 2) / 2A = -V0 ^ 2 / (2 * (-g)) = -20 ^ 2 / (2 * (- 10)) = 20 m.

Answer: The specified body will be able to rise to a height of 20 meters.
