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.
What is the distance between the centers of the two slits? Describe answer in m.

What frequency will hear after the train passes
A 2.30-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.40sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 35.0 N/m.
