Block A on the left has mass 1.00 kg. Block B on the right has mass 3.00 kg. Block A is initially moving to the right at 6.00 m/s, while block B is initially at rest. The surface they move on is level and frictionless. What is the velocity of the center of mass of the two blocks after the blocks collide? A. 6.00 m/s, to the right B. 3.00 m/s, to the right C. 1.50 m/s, to the right D. zero

While driving his car five miles over the speed limit, Carl struck Darla, who was jaywalking across the street. When the case came to trial, the jury determined that Carl was 60% negligent and that Darla was 40% negligent. Darla’s injuries are $10,000. This accident occurred in a state following the comparative negligence theory of recovery.

Two objects with different masses collide with and stick to each other. Compared to before the collision, the system of two objects after the collision has: A. the same amount of total momentum and the same total   kinetic energy. B. the same amount of total momentum but less total kinetic   energy. C. less total momentum but the same amount of total kinetic   energy. D. less total momentum and less total kinetic energy.

Two blocks are connected as shown. When released, the 6.00-kg block accelerates downward and the 8.00-kg block accelerates to the right. After each block has moved 2.00 cm, the force of gravity has done: A. work on both blocks, but more work on the 8.00-kg   block than on the 6.00-kg block. B. the same amount of work on both blocks. C. work on both blocks, but less work on the 8.00-kg block   than on the 6.00-kg block. D. work on the 6.00-kg block only.
