  • Assuming that the "monkey" in the "Shoot the Monkey" demonstration is 5.0 meters from the hunter and drops from a tree 2.0m above his head, confirm that the hunter hits the monkey by aiming directly at him.

  • A group of Physics 11 students note that Professor Smith walks beneath their dorm window each morning at precisely 7:45:00.0am on the way to his office. During breakfast they sneak into the kitchen and steal a raw egg which they conspire to drop on his head. Professor Smith is 1.8 meters tall and walks at a pace of 2.0 m/s. The dorm window is 12m above the sidewalk. At what time should the students release the egg? Where will Prof. Smith be at that time?
