A ball weighing 0.05 kg after impact acquired a speed of 16 m / s. What kinetic energy did the ball receive?

To find out the kinetic energy received by the specified ball, we use the formula: Ek = 0.5 * mm * V ^ 2, where mm is the mass of the specified ball (mm = 0.05 kg); V – acquired speed (V = 16 m / s).

Let’s perform the calculation: Ek = 0.5 * mm * V ^ 2 = 0.5 * 0.05 * 16 ^ 2 = 6.4 J.

Answer: After the impact, the specified ball should have acquired a kinetic energy of 6.4 J.
