Read and understand two-dimensional kinematics as described in Chapter 3
§1 - 6. Pay special attention to vectors which we will only touch
on in class.
Ch. 3 - Problems: 2, 15, 18, 23, 24, 30, 39, 58.

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?
