Two inelastic bodies weighing 25 kg and 10 kg, moving towards each other at a speed of 0.5

Two inelastic bodies weighing 25 kg and 10 kg, moving towards each other at a speed of 0.5 m / s and 0.1 m / s. What is their speed after the collision?

Initial data: m1 (mass of the first body) = 25 kg; m2 (mass of the second body) = 10 kg; V1 (speed of the first body) = 0.5 m / s; V2 (speed of the second body) = 0.1 m / s; the bodies are inelastic, the movement is oncoming.

For an inelastic impact, the following expression will be true: m1 * V1 – m2 * V2 = (m1 + m2) * V1.2, whence V1.2 = (m1 * V1 – m2 * V2) / (m1 + m2).

Let’s calculate: V1.2 = (25 * 0.5 – 10 * 0.1) / (25 + 10) = 11.5 / 35 = 0.329 m / s.

Answer: The speed of inelastic bodies after collision will be 0.329 m / s.
