The body falls from a height of 30 m. Determine the speed at the moment of landing.

Task data: h (fall height, distance traveled) = 30 m.
Reference values: g (acceleration due to gravity) = 9.81 m / s2.
The speed of the body in question at the moment of landing can be expressed from the equality: m * g * h = m * V ^ 2/2, whence V = √ (2 * g * h).
Let’s do the calculation: V = √ (2 * 9.81 * 30) = 24.261 m / s ≈ 24.3 m / s.
Answer: At the moment of landing, the speed of the body in question will be 24.3 m / s.
