A projectile is fired from a horizontal spring-loaded gun aimed directly (along the line of sight) at a distant bull’s eye. Because of the pull of gravity during flight, the projectile misses and hits a point at distance y beneath the bull’s eye. To hit the bull’s eye, the gun should be aimed along a line of sight above the bull’s eye, a vertical distance 1. of y, exactly.2. slightly lower than y.3. slightly higher than y.

Consider the pair of identical blocks about to be simultaneously released from rest. Block A is completely free, and Block B is attached to one end of a massive chain, the other end held as shown.When dropped, both blocks hit the floor below—a vertical distance equal to the length of the chain.Which block hits first? 1. Block A2. Block B
