Examine the scenario.

A sports car starts from rest and uniformly accelerates to a speed of 60 km/h in 6 s. The car moves east the entire time.

Which option represents a vector quantity present in the scenario?

acceleration: 10 km/h/s east

speed: 60 km/h

velocity: 10 km/h/s east

distance: 60 km

Answer;

-Acceleration: 10 km/h/s east

Explanation;

-The quantity is either a vector or a scalar. Scalars are quantities that are fully described by a magnitude (or numerical value) alone while Vectors are quantities that are fully described by both a magnitude and a direction.

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

In this case, a = (v-u) / t; where a is the acceleration, v is the final velocity, u is the initial velocity and t is time.

a = (60 - 0) / 6

= 10 km/h/s
