- Lately, Jason has been taking drivers' ed so that he can get his license. However, he's also been taking physics, and so he wonders what his acceleration is, when he drives on a circular path in an empty parking lot near Peachtree Mall with diameter 78.0 m, if he is driving at a constant speed of 23.0 m/s. What is his acceleration? O 66.1 m/s² 13.6 m/s2 O 0.590 m/s² O 1.70 m/s² O 0 m/s²As the moon moves around the earth at a mean orbital velocity of 1.022 km/s is the moon accelerating? O No, because acceleration is a vector. No, because the net displacement is zero. O Yes, because the speed is not constant. Yes, because the velocity is not constant.If you double the radius of an object in uniform circular motion, how does its centripetal acceleration change? O It decreases by a factor of 2.
