18. Suppose you are on the Moon and you have a rifle. You fire the rifle horizontally. What speed must the bullet exit the gun barrel for it to orbit the Moon in a circle and come back and hit you (if you didn't duck your head)? Assume it doesn't hit any mountains on the moon. The bullet has a mass of 2 grams and the gun has a mass of 4 kg. 19. In the diagram below, all surfaces have a coefficient of static and kinetic friction of 0.6 and 0.53, respectively. Block 1 has a mass of 12 kg. Blocks 2 and 3 each have a mass of 20 kg and are connected by a lightweight rope. All the blocks are stationary. Determine the amount of force, F, required to get the blocks moving. How much force, F. is needed to cause the blocks to move right at constant velocity and before block 1 falls off block 2? Determine the tension in the rope when they are moving to the right, in this latter case, at constant velocity. F 2 3
