Question

Meg walks with a velocity of 0.9 m/s west. She does so while riding on a train that is traveling with a velocity of 2.7 m/s east. What is Megs velocity? A. 3.6 m/s west B. 1.8 m/s west C. 1.8 m/s east D. 3.6 m/s east

Answer 1

Velocities are vectors so we can add them!

Let's let +x be East and -x be West.

-0.9 + 2.7 = 1.8

Since our answer is positive that means East so the answer is C.
