Relative Motion and Frames of Reference

Today we started the class by listening to announcements, then looked at Brittney's and Garrison's wall posts. After that we read a writing in the textbook about Relative Motion and Frames of Reference.

Relative motion is the motion of an object, like a car, relative to another object, like the ground.

Example: The air speed of a small plane is 200. km/h. The wind speed is 50. km/h from the east (therefore, blowing west). Determine the velocity of the plane relative to the ground if the pilot keeps the plane pointing in the following direction :

East- pVa= 200.km/h [E] pVg= pVa + aVg
aVg= 50. km/h [W] = 200. km/h[E] + 50. km/h[W]
pVg= ? = 150. km/h [E]
