Задача 10380.

A ball of mass m1 = 1 kg collides with a ball at rest and transfers half of its kinetic energy to it. Considering the impact to be central, absolutely elastic, determine the mass of the second ball in two cases: (a) m1 is greater than m2; (b) m1 is less than m2.

A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
