1.A 500 g piece of silver at 150oC is submerged in 1000 g of water at 5oC to be cooled. Determine the final temperature of the silver and water. [The specific heat capacity of water is 4.18 x 103 J/kgoC and the specific heat capacity of silver is 2.4 x 102 J/kgoC.]

2. A toboggan carrying 2 children has a total mass of 85 kg. It reaches its maximum speed at the bottom of a hill, and then glides to a stop in 21 m along a horizontal surface. Calculate the work done by the kinetic friction if the coefficient of kinetic friction between the toboggan and the snowy surface is 0.11.
