Task id10328
A ball with a mass of 70 g is at rest, and another ball of the same size, but with a mass of 150 g, hits it with a speed of 44 cm/s so that the speed of its center lies on the tangent to the surface of the stationary ball. Find the speed (in cm/s) of the impacting ball after a perfectly elastic impact. The surfaces of the balls are smooth.
