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

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

3 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 belowa vertical distance equal to the length of the chain. Which block hits first? 1. Block A 2. Block B
