Respuesta :

zzv

Answer:

A

Explanation:

Acceleration and velocity are vector quantities so they have a magnitude and direction. If the car is travelling in a circle it is constantly changing its direction therefore it is acclerating.

When A car driving in a circle at a constant speed of 35 mph then car is accelerating.

Option A is correct.

Scalar quantity A quantity which have only magnitude.

Vector quantity A quantity which have both magnitude and direction.

  • Acceleration and velocity both are vector quantities so they have a magnitude and direction.
  • When  the car is travelling in a circle it is constantly changing its direction.

Hence, when A car driving in a circle at a constant speed of 35 mph then car is accelerating.
