If a freely falling object were somehow equipped with a speedometer on a planet where the acceleration due to gravity is 20 m/s2, then its speed reading would increase each second by
A)10 m/s.
B)20 m/s.
C)30 m/s.
D)40 m/s.
E)depends on its initial speed

Question

Quizplus · Accepted Answer

The speed of a freely falling object increases by the acceleration due to gravity each second. Since the acceleration is given as 20 m/s^2, the speed increases by 20 m/s each second, regardless of its initial speed.
