Question

шар массой 4 кг движется со скоростью v1= 5 м/с и сталкивается с шаром массой 6 кг, который движется навстречу ему со скоростью v2=3 м/с. Какова скорость u1 и u2 шаров после удара? Удар считать абсолютно упругим, прямым, центральным.

Answer 2

Problem Analysis

We are given two balls, one with a mass of 4 kg and the other with a mass of 6 kg. The first ball is moving with a velocity of 5 m/s, while the second ball is moving towards it with a velocity of 3 m/s. We need to determine the velocities of both balls after the collision. The collision is assumed to be perfectly elastic, direct, and central.

Solution

To solve this problem, we can use the principle of conservation of momentum and the principle of conservation of kinetic energy.

According to the principle of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision. Mathem
