2. In:
A rock is dropped off a cliff and strikes the ground with an impact velocity of 30 m/s. How high was the cliff?
15 m
20 m
30 m
45 m
60 m

3. Objective:
To begin our study of 2 dimensional motion.

4. Homework check

6. 2 dimensional motion Must be solved using vectors Displacement vectors
Velocity vectors
Acceleration vectors
Force vectors

7. Combining vectors
Only the same type of vector can be combined.

9. Components of vectors

12. Vector problem set

15. Out:
A sailboat is heading due west at 10 m/s. The wind is blowing at 5 m/s to the north. What is the actual velocity of the boat?
