Question

The acceleration of the car is to the east. slowing down The acceleration of the car is to the west. speeding up Consider the velocity vs. time graphs for two objects. Does either object ever turn around? If so, identify the time or times. Explain briefly in either case. Is there a time when both objects are speeding up? If so, identify the time or times. Explain briefly in either ease. Is the acceleration of object ? positive, negative, or zero at t = 7 s? Explain briefly. A velocity-time graph is shown for a cat moving along a fence. At which of the labeled points, if any, is the acceleration zero? Explain briefly. Yes, the slope of Bis zero
