At the end of 1/2 second an apple freely falling from rest has a speed of
A)1 m/s.
B)5 m/s.
C)10 m/s.
D)more than 10 m/s.

Question

Quizplus · Accepted Answer

The acceleration due to gravity is approximately 9.8 m/s^2. Using the equation v = gt for an object in free fall (where v is the final velocity, g is the acceleration due to gravity, and t is the time), after 0.5 seconds, the speed v = 9.8 m/s^2 * 0.5 s = 4.9 m/s. The closest answer is 5 m/s.
