Question

A helicopter is traveling west at 80 mph. It is moving above a car traveling on a highway at 80 mph. Which of the following statements is true?

Both measurements are scalar quantities.
Both measurements are vector quantities.
The helicopter's measurement is a scalar, and the car's measurement is a vector.
The helicopter's measurement is a vector, and the car's measurement is a scalar.

Answer 1

D The helicopter's measurement is a vector, and the car's measurement is a scalar.

Step-by-step explanation:

I took the physics exam

Answer 2

Answer: The helicopter's measurement is a vector, and the car's measurement is a scalar.

Explanation: To be a vector quantity, both a direction and magnitude must be given. In this case, it is traveling 80 mph west, both a direction and magnitude. For the car, it is scalar because only the magnitude of 80 mph is given.
