September 21, 2021 | education

| The given problem: m (the mass of the soccer ball under consideration) = 450 g (in the SI system m = 0.45 kg); V (ball flight speed) = 25 m / s.

To determine the kinetic energy of the soccer ball under consideration, we use the formula: Ek = m * V² / 2.

Let’s calculate: Ek = 0.45 * 25² / 2 = 140.625 J.

Answer: The soccer ball in question has a kinetic energy of 140.625 J.
