The acceleration due to gravity is 10 m/sec². If an object falls from rest, its instantaneous speed at the end of the fifth second is (neglecting air resistance) A) 100 m/sec. B) 5 m/sec. C) 10 m/sec. D) 50 m/sec. E) impossible to determine from the given information.

Question

Quizplus · Accepted Answer

The speed of an object in free fall from rest is given by the formula v = gt, where g is the acceleration due to gravity (10 m/s²) and t is the time in seconds. After 5 seconds, v = 10 m/s² * 5 s = 50 m/s.
