A body has a constant acceleration of 10 ft/s², an initial speed of 10 ft/s, and a final speed of 30 ft/s. Its speed is never zero. Its average speed is A) 10 ft/s. B) 20 ft/s. C) 30 ft/s. D) 40 ft/s.

Question

Quizplus · Accepted Answer

The average speed of an object is given by the total distance traveled divided by the total time taken. In this case, since the acceleration is constant, the average speed can also be calculated as the average of the initial and final speeds. Thus, average speed = (initial speed + final speed) / 2 = (10 ft/s + 30 ft/s) / 2 = 20 ft/s.
