Two balls with the masses M1 = 3 kg and m2 = 2 kg moving along one straight line with speeds V1

Two balls with the masses M1 = 3 kg and m2 = 2 kg moving along one straight line with speeds V1 = 2 m / s and V2 = 1 m / s towards each other, they experience an absolutely elastic collision. Find the maximum value of the energy of the elastic deformation of the balls during this collision.

We will find the values of the kinetic energies of the balls, for this we use the formula:

W = M * V ^ 2/2, where m is a mass, V is the speed of the ball.

W1 = 3 * 2 ^ 2/2 = 6 J;

W2 = 2 * 1 ^ 2/2 = 1 J.

At the time of the collision, the kinetic energy of balls will be zero, then according to the law of conservation, the energy of their deformation will be equal to the sum of their kinetic energies:

6 + 1 = 7 J.

Answer: The desired value of energy is 7 J.
