Solve.The following graph represents the speed of a truck as a function of time.
a.When does the truck stop accelerating?b. For how long does the truck maintain a constant speed?
A. a. The truck stops accelerating when the speed stops increasing. Thus, the truck stops accelerating after 8 seconds. b. The truck has a constant speed when the graph is horizontal. Thus, the car maintains a constant speed for 24 seconds. B. a. The truck stops accelerating when the speed stops increasing. Thus, the truck stops accelerating after 8 seconds. b. The truck has a constant speed when the graph is horizontal. Thus, the car maintains a constant speed for 12 seconds. C. a. The truck stops accelerating when the speed stops increasing. Thus, the truck stops accelerating after 8 seconds. b. The truck has a constant speed when the graph is horizontal. Thus, the car maintains a constant speed for 8 seconds. D. a. The truck stops accelerating when the speed stops increasing. Thus, the truck stops accelerating after 8 seconds. b. The truck has a constant speed when the graph is horizontal. Thus, the car maintains a constant speed for 16 seconds.
