One-half second after starting from rest, a freely falling object will have a speed of about
A)5 m/s.
B)10 m/s.
C)15 m/s.
D)none of the above

Question

Quizplus · Accepted Answer

The speed of a freely falling object is given by the equation v = gt, where g is the acceleration due to gravity (approximately 9.8 m/s²) and t is the time in seconds. After 0.5 seconds, v = 9.8 m/s² * 0.5 s = 4.9 m/s, which is approximately 5 m/s.
