Question

Examine the scenario.

A car starts from rest and uniformly accelerates to a speed of 30 mi/h in 6 s. The car moves north the entire time.

Which option correctly lists a vector quantity from the scenario?

distance: 30 mi

acceleration: 5 mi/h/s north

speed: 30 mi/h

velocity: 5 mi/h/s north

Answer 1

acceleration: 5 mi/h/s north

Explanation:

Distance and speed are not vector quantities. (There is no direction associated with them.)

The units of velocity are distance/time, not distance/time², so that choice is incorrect.

The correctly described vector is that of acceleration.
