A body weighing 4 kg freely falls from a height of 30 m. What is the kinetic energy of the body at the lowest point of fall?
Task data: m (mass of the falling body) = 4 kg; h (original height) = 30 m.
Constants: g (acceleration due to gravity) ≈ 10 m / s2.
To find the value of the kinetic energy at the lowest point of incidence, we use the formula: Ek = Ep (energy conservation law) = m * g * h.
Calculation: Ek = 4 * 10 * 30 = 1200 J.
Answer: at the lower point of the fall of a given body, the kinetic energy was 1200 J.
