In which situation are both the speed and velocity of the car changing? a) the car turns left at 5 m s . b) the car travels down a straight track at 30 m s . c) the car travels around a circular track at 30 m s . d) a car traveling at 30 m s slows to 15 m s and turns the corner.

Answer is A because the speed and velocity would change. Think of it as GTA, your going 30+ miles per hour and you take a left turn, the speed and velocity would change in an instant..
