One car travels due east at 40 km/h. and a second car travels north al 40 km/h. Arc their velocities equal? Explain.
Whether the velocities of the cars are equal or not.
Answer to Problem 1Q
The velocities of the cars are not equal since their direction of motion are different.
Explanation of Solution
Velocity is a vector quantity. It have both magnitude and direction. If two objects are said to be moving with same velocity, they must have same speed (magnitude of velocity) and they must be moving in the same direction.
In the given situation, one car is moving at
