The body is thrown horizontally at a speed of 3 m / s. The flight range of the body is 6 m. From what height is the body thrown?

Task data: Vg (horizontal throw speed) = 3 m / s; Sg (horizontal path distance) = 6 m.

Constants: g (acceleration due to gravity) ≈ 10 m / s2.

1) The duration of the fall: t = Sg / Vg = 6/3 = 2 s.

2) The height of the body at the moment of the horizontal throw: h = g * t ^ 2/2 = 10 * 2 ^ 2/2 = 20 m.

Answer: The horizontal throw of the body was made at a height of 20 m.
