Which of the following is an example of a vector?14 miles per hour.68 newtons per coulomb.15 meters per second. 25 N82 miles per hour west.

Break Down the Problem

1. Define what constitutes a vector.
2. Analyze the options given to determine which represents a vector.

Relevant Concepts

1. A vector is a quantity that has both magnitude and direction.
2. Examples include velocity (speed with direction) and force (magnitude with direction).

Analysis and Detail

1. 14 miles per hour - This is a scalar quantity (just a speed, no direction).
2. 68 newtons per coulomb - This is also a scalar quantity; it represents electric field strength but does not have a directional component in this form.
3. 15 meters per second - Again, this is a scalar quantity (speed without direction).
4. 25 N - This is a scalar quantity representing force but lacks direction.
5. 82 miles per hour west - This is a vector quantity because it specifies both speed (magnitude) and direction (west).

Verify and Summarize

Comparing each option, the only expression that describes both a magnitude and a direction is "82 miles per hour west."

Final Answer

82 miles per hour west is an example of a vector.
