Problem: A pinball bounced around its machine before resting between two bumpers. Before the ball came to rest, its displacement (all angles measured up from x axis) was recorded by a series of vectors. 83 cm at 90° 55 cm at 159° 69 cm at 227° 47 cm at 287° 63 cm at 21°.
Part A: Determine the total displacement's magnitude and direction?
I know the correct answer but explain how to get this answer!
