A 280-g metal container, insulated on the outside, holds 140 g of water in thermal equilibrium at 22°C. A 22-g ice cube, at 0.0°C, is dropped into the water, and when thermal equilibrium is reached the temperature is 15°C. Assume there is no heat exchange with the surroundings.
What is the specific heat of the metal container?
To understand the vector nature of momentum in the case in which two objects collide and stick together. In this problem we will consider a collision of two moving objects such that after the collision, the objects stick together and travel off as..
