1 August 27 AP physics

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?
