Question1

To measure weight of the cat, a person places a 100 N box and a 60 N box from the ends of a uniform pole that is pivoted at its center. The system balances when the cat stands at a point of the rods length from the 60 N boxes. What is the estimated mass of the cat?

Question2

Atoms can be cooled by multiple laser beams. in such an experiment, the temperature of sodium atoms can be cooled to 0.1 mK. What is rms speed of the atoms at this temperature? The atoms can be held trapped for about 1 s in a 1 cm trap. Estimate this time with the time for one of the atoms to wonder out of the trap if there was no trap action.
