Description
A car moves from the point (3.0 m) xˆ + (5.0 m) yˆ to the point (8.0 m) xˆ - (7.0 m) yˆ in 2.0 s. What is the
direction of the average velocity of the car?

Explanation & Answer
Thank you for the opportunity to help you with your question!
Average velocity= distance/time
Average velocity=[ (8.0 m) xˆ - (7.0 m) yˆ] - [(3.0 m) xˆ + (5.0 m) yˆ]/2
Average velocity= [ (5 m) xˆ- (12 m) yˆ]/2
Average velocity= [ (2.5 m) xˆ- (6 m) yˆ]
