A1.0 kg block is placed against an ideal spring with spring constant 800 n/m and initially compressed 0.20 m. the spring and block lie on a frictionless 30 degree incline. the system is then released from rest and the block slides up the incline. how far from the release point does the mass slide before momentarily coming to rest (reaching its maximum height)?

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.
