Read the scenario. A car travels 25 m/s forward for 10 s. Which option accurately identifies the measurements within the scenario that are vector quantities and describes why?

a. The measurements 25 m/s and 10 s are vector quantities because these numbers are both measurements that do not include direction.

b. The measurement 10 s is the only vector quantity because it measures time.

c. The measurement 25 m/s is the only vector quantity because it is a measurement of speed.

d. The measurement 25 m/s forward is the only vector quantity because it is a measurement that includes a direction.

Madden Oconnell · Answer 1

It is given that,

A car travels 25 m/s forward for 10 s.

Solution,

For a vector, a quantity must have both magnitude as well as the direction. For a scalar, a quantity have only the magnitude. In this case, the car moves in forward direction. This is the only difference between the vector and the scalar.

Out of given option, s the correct option is (c) "The measurement 25 m/s is the only vector quantity because it is a measurement of speed".
