Bir xil mayatnik yuklari to‘qnashadi
Two identical bobs, each of mass 2.0 kg, hang side by side on strings of equal length. One is pulled aside to a height h = 20 cm and released; it strikes the other bob at the lowest point and they stick together.

How high, in cm, do the joined bobs rise?
Har birining massasi 2.0 kg bo‘lgan ikki bir xil yuk teng uzunlikdagi iplarda yonma-yon osilgan. Ulardan biri h = 20 cm balandlikka chetga tortilib qo‘yib yuboriladi; u eng quyi nuqtada ikkinchi yukka urilib, ular bir-biriga yopishib qoladi.
