Question

car a travels from new york to miami at 25 m/s. car b travels from new york to chicago, also at 25 m/s. car a and car b have ________ speeds and ________ velocities.
a equal, equal
b equal, different
c different, equal
d different, different

Explanation:

Step1: Define speed and velocity

Speed is a scalar quantity, only has magnitude. Both cars have a magnitude of 25 m/s, so speeds are equal.

Step2: Analyze velocity

Velocity is a vector quantity, has both magnitude and direction. Cars are moving to different cities (Miami and Chicago), so directions are different, and velocities are different.

Answer:

B. equal, different
