A 2.9 g bullet moving at 309 m/s strikes a stationary block with a mass of 2.55 kg. If the bullet passes through the block and continues moving at a speed of 48 m/s, how fast is the block moving after the bullet hits it? Remember, the mass must be in kilograms. Report the answer to 4 decimal places. Please do not include units or the answer will be marked incorrect.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
