Q1. What will be the equilibrium temperature when a 223 g block of copper at 258 C is placed in the 178 g aluminium calorimeter cup containing 874 g of water at 13.2 C?

Q2. A car moves along an x axis through a distance of 800 m, starting at rest (at x = 0) and ending at rest (at x = 800 m). Through the first of that distance, its acceleration is +2.25 m/s2. During the next of that distance, its acceleration is -0.750 m/s2. What are (a) its travel time through the8 m and (b) its maximum speed? (c) Diagram position x, velocity v, and acceleration a versus time t for the trip.
