Q1. A 35.0-g bullet moving at 475 m/s strikes a 3.2-kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 225 m/s. How fast is the bag moving while the bullet exits?

Q2. Two point charges are placed on the x axis. The first charge, = 8.00, is placed a distance 16.0 from the origin along positive x axis; the second charge, = 6.00, is placed a distance 9.00 from the origin along negative x axis. Compute the electric field at point A, located at coordinates (0m, 12m).
