A motorcycle goes north at 40 miles per hour. A car goes south at 40 miles per hour on the same street. Which statement is true?

Question

The vehicles have the same speed, but different velocity
The vehicles have the same speed and velocity
The vehicles have the same velocity, but not the same speed
The vehicles are going in opposite directions, so their speed is not the same

Answer 1

The correct statement is:

The vehicles have the same speed, but different velocity.

Speed is a scalar quantity that only considers how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. In this case, both the motorcycle and the car are traveling at 40 miles per hour, which means they have the same speed, but they are moving in opposite directions (north and south), so their velocities are different.

Answer 2

A. The vehicles have the same speed, but different velocity.

Answer 3

Yes, that's correct!

The vehicles indeed have the same speed of 40 miles per hour, but since they are moving in opposite directions, their velocities are different. Speed is a measure of how fast something is moving without regard to its direction, while velocity includes both speed and direction. Therefore, the statement "The vehicles have the same speed, but different velocity" is accurate.
