Find the kinetic energy of a 2 kg hare running at a speed of 54 km / h.
| June 24, 2021 | education
To find out the kinetic energy of the presented hare, we apply the formula: Ek = 0.5 * m * V ^ 2.
Data: m – weight of the presented hare (m = 2 kg); V – speed of running, movement (V = 54 km / h, in SI system V = 15 m / s).
Let’s calculate: Ek = 0.5 * m * V ^ 2 = 0.5 * 2 * 15 ^ 2 = 225 J.
Answer: The kinetic energy of the presented hare is 225 J.
