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 acceleration due to gravity is the rate at which the velocity of an object changes during free fall. Therefore, the speedometer reading would increase each second by the acceleration due to gravity, which is 20 m/s/s. Therefore, the correct answer is B.
