Given: m (mass of the considered hockey puck) = 160 g (in SI m = 0.16 kg); V (puck speed in flight) = 20 m / s.
To determine the kinetic energy of the considered hockey puck, we use the formula: Ek = m * V ^ 2/2.
Let’s calculate: Ek = 0.16 * 20 ^ 2/2 = 32 J.
Answer: In flight, the hockey puck in question had a kinetic energy of 32 J.
