Question

A car makes a trip due north for three-fourths of the time and due south one-fourth of the time. The average northward velocity has a magnitude of 32 m/s, and the average southward velocity has a magnitude of 29 m/s. What is the average velocity (magnitude and direction) for the entire trip?

Answer 1

16.75 m/s North

Step-by-step explanation:

Calculate a weighted average; North is the positive direction

(32 m/s).75 - (29 m/s).25 = 16.75 m/s N
