Question

Как найти скорость, зная массу и скорость? Поясню: в задаче дано m1 и m2, а так же u1. Нужно найти вторую скорость. Дайте формулу, пожалуйста.

Answer 1

При упругом столкновении m1/m2=V2/V1

Answer 2

Finding Velocity Knowing Mass and Velocity

To find the second velocity (v2) when given the masses (m1 and m2) and the initial velocity (u1), you can use the following formula:

v2 = (2 * m1 * u1) / (m1 + m2)

This formula is derived from the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant if no external forces act on it.

This formula allows you to calculate the final velocity of the two masses after an elastic collision, assuming no external forces are involved.

I hope this helps! If you have any further questions, feel free to ask.
