Plasticine balls are flying towards each other. the modules of their impulses are 0.03 kgm / s and 0.04 kgm / s

Plasticine balls are flying towards each other. the modules of their impulses are 0.03 kgm / s and 0.04 kgm / s, respectively. colliding balls stick together and the momentum of sticking balls is equal.

Task data: P1 (impulse of the first plasticine ball) = 0.03 kg * m / s; P2 (impulse of the second plasticine ball) = 0.04 kg * m / s; balls were moving towards each other; absolutely inelastic blow.

The momentum of the stuck together plasticine balls can be determined by the formula (we consider the direction of motion of the second plasticine ball to be positive): P = P2 – P1.

Let’s make a calculation: P = 0.04 – 0.03 = 0.01 kg * m / s.

Answer: The required impulse of the stuck together balls is 0.01 kg * m / s.
