Suppose that an insulating container of negligible mass contains 0.12 kg of water at a temperature of 4 degrees C. Now suppose 178 g of ice initially at a temperature of -39 degrees C is added to the water. Assuming no transfer of heat to or from the surroundings, what is the final mass (in kg) of the water in the system?
At one instant a bicyclist is 53m due east of a park's flagpole, going due south with a speed of 12m/s. Then 37s later, the cyclist is 53m due north of the flagpole, going due east with a speed of 12m/s. For the cyclist in this 37s interval.
