You are riding your bike around town and are trying to go as fast as you can to beat your friend in a race. If the combined mass of you and the bike is 75 kg, and your acceleration is 2.2 m/s2, what is the net force on the bike?

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.
