Two buses depart from chicago, one going to new york and one to san francisco. each bus travels at a speed of 30 m/s. do they have equal velocities? explain.

They don't have equal velocities

Explanation:

We have one bus travelling from Chicago to New York at 30 m/s and one bus travelling from Chicago to San Francisco at 30 m/s.

This is a cheat question. You need to remember that velocity  is a vector. Remember that a vector has a direction and a module. So, the answer will be true, if both buses meet both conditions (direction and module). Let's start to analyze:

Module: In this case is 30 m/s for both buses

Direction: In this case is where the buses are heading. One is going to New York, and one is going to San Francisco. So the directions are different.

As module and direction are not the same for both buses we can say that they don't have equal velocities.

a and c

c is 100% but i am confused in a

like poles repel so keep pushing north to north and repels funny to see this
