a racecar driver circles a racetrack with a constant speed of 110 km/hr. which best describes the speed and velocity of the car? a the speed and velocity remains constant. b the speed is constant and velocity is changing. c the speed has no impact on the velocity of the car. d the velocity changes only if the car slows down or speeds up.

Explanation:

Speed is a scalar quantity representing how fast an object is moving. Velocity is a vector quantity that includes both speed and direction. Since the car is moving in a circle, its direction is constantly changing while its speed is constant at 110 km/hr.
