B ning massasini toping
As shown in the figure, an object A of mass 1 kg on a frictionless horizontal surface collides head-on with a stationary object B. Initially A moves at 2 m/s to the right. After the collision, A moves at 1 m/s to the left and B moves at 1 m/s to the right.

What is the mass of object B?
Rasmda ko‘rsatilganidek, ishqalanishsiz gorizontal sirtdagi massasi 1 kg bo‘lgan A jism tinch turgan B jism bilan markaziy to‘qnashadi. Dastlab A o‘ngga 2 m/s tezlik bilan harakatlanadi. To‘qnashuvdan so‘ng A chapga 1 m/s, B esa o‘ngga 1 m/s tezlik bilan harakatlanadi.
