Head-On Collision: Speed of A
Difficulty: Easy · Topics: Momentum, Conservation of Momentum, Collisions
Markaziy to‘qnashuv: A ning tezligi
As shown in the figure, objects A and B with masses of 1 kg and 2 kg collide head-on, each with a speed of 3 m/s, and then move in opposite directions on a frictionless floor. The speed of B after the collision is 1 m/s.

What is the speed of object A after the collision?
Rasmda ko‘rsatilganidek, massalari 1 kg va 2 kg bo‘lgan A va B jismlar har biri 3 m/s tezlik bilan to‘qnashadi, so‘ng ishqalanishsiz polda qarama-qarshi tomonlarga harakatlanadi. To‘qnashuvdan keyin B ning tezligi 1 m/s.
