Q. In a physics lab experiment a student immersed 200 onecent coins (each having a mass of 3.00 g) in boiling water. After they reached thermal equilibrium, she fished them out and dropped them into 0.240 kg of water at 20.0C in an insulated container of negligible mass. What was the final temperature of the coins?

Q. A toy train is pushed forward and released at = 4.0 with a speed of 2.5 . It rolls at a steady speed for 3.0 , then one wheel begins to stick. The train comes to a stop 9.4 from the point at which it was released. What is the train's acceleration after its wheel begins to stick?
