A train with constant velocity of 60km/hour travels east for 40minutes; then in a direction 50degrees east of north for 20minutes; then west for 50minutes. A)What are the magnitude and B) angle of its average velocity during the trip?
Homework Equationssinx; cosx; tanx<-- I think.
The Attempt at a Solution
My main trouble is finding out what the question is asking. I have determined that the magnitudes of each are 40km;20km;50km respectively.
I have drawn each vector on a cartesian coordinate plane such that they start at the origin and then connect tip to tail. IS the displacement vector the one that extends from the origin to the tip of the last one drawn?
This is my first post so I apologize if it is difficult to follow. Is there a way I could have drawn this w/out a scanner? Thanks.
