A hockey puck weighing 160 grams flies at a speed of 20 m / s to find kinetic energy.

Initial data: m (mass of the hockey puck) = 160 g (0.16 kg); V (the speed at which the puck flies) = 20 m / s.

The kinetic energy of a hockey puck can be determined by the formula: Ek = m * V ^ 2/2.

Let’s perform the calculation: Ek = 0.16 * 20 ^ 2/2 = 32 J.

Answer: A hockey puck has a kinetic energy of 32 J.
