Two Carts Couple Together
Difficulty: Easy · Topics: Perfectly Inelastic Collisions, Momentum
Ikki aravacha tirkaladi
As shown, a cart of mass m moves at speed v on a frictionless horizontal surface and collides with another cart of mass m at rest. They become one body and move together along the same line.

What is their speed after the collision?
Rasmda ko‘rsatilganidek, m massali aravacha ishqalanishsiz gorizontal sirtda v tezlik bilan harakatlanib, tinch turgan m massali boshqa aravacha bilan to‘qnashadi. Ular bitta jismga aylanib, o‘sha chiziq bo‘ylab birga harakatlanadi.

To‘qnashuvdan keyin ularning tezligi nimaga teng?
