If a motorcycle racer is traveling at a constant speed of 16 m/s around the track and is going around a curve, why is the rider changing velocity if speed stays the same?

• Because the rider is accelerating.

• Because the rider is changing direction.

• Because the rider is slowing down.

• Because the rider is moving in a straight line.
