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
