The gain in speed each second for a freely-falling object is about
A)0 m/s.
B)5 m/s.
C)10 m/s.
D)20 m/s.
E)depends on the initial speed.

Question

Quizplus · Accepted Answer

The gain in speed each second for a freely-falling object is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 or 10 m/s (rounded to one significant figure). Therefore, the best choice is C, as it is the closest value to the acceleration due to gravity. Option E is not correct as the initial speed does not affect the acceleration of the object due to gravity, only the initial velocity.
