Question

five students were asked to come up with examples of velocity, and their results are displayed in the table below. which students created accurate examples of velocity? select two correct answers.
student 5: 6 m/s
student 4: 5 m/s southeast
student 3: 25 m/s²
student 2: 15 m/s north
student 1: 8 m/s
student: example

Explanation:

Step1: Recall the definition of velocity

Velocity is a vector quantity, which means it has both magnitude and direction.

Step2: Analyze each student's answer

• Student 1: Only has magnitude ($8\ m/s$), no direction. So it is not velocity (it is speed).
• Student 2: Has magnitude ($15\ m/s$) and direction (north). This is a valid velocity.
• Student 3: The unit is $m/s^{2}$, which is the unit of acceleration, not velocity.
• Student 4: Has magnitude ($5\ m/s$) and direction (southeast). This is a valid velocity.
• Student 5: Only has magnitude ($6\ m/s$), no direction. So it is not velocity (it is speed).

Answer:

Student 2 and Student 4
