Notice that all the initial spring potential energy was transformed into gravitational potential energy. if you compressed the spring to a distance of 0.200 m , how far up the slope will an identical ice cube travel before reversing directions? note that the spring is compressed twice as much as in the original problem.

On a mild saturday morning while people are working inside, the furnace keeps the temperature inside the building at 23degreesc. at noon the furnace is turned off, and the people go home. the temperature outside is a constant 16degreesc for the rest of the afternoon. if the time constant for the building is 3 hr, when will the temperature inside the building reach 18degreesc? if some windows are left open and the time constant drops to 2 hr, when will the temperature inside reach 18degreesc?
