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

Answer 1

it is equal and different so B

Answer 2

B) equal, different

Step-by-step explanation:

- Speed is the ratio between the distance covered by an object and the time taken:

`v=(d)/(t)`

And it is a scalar, because it has only a magnitude, so it does not depend on the direction of the motion.

- Velocity is instead a vector, consisting of a magnitude (which is equal to the ratio between the displacement and the time taken:

`v=(s)/(t)`

and a direction.

In this problem, the two cars have same speed (25 m/s) but different velocities, because they travel in different directions.
