An object falls freely from rest on a planet where the acceleration due to gravity is 20 m/s². After 5 seconds, the object will have a speed of A)5 m/s. B)10 m/s. C)20 m/s. D)50 m/s. E)100 m/s.

Question

Quizplus · Accepted Answer

The speed of a freely falling object can be calculated using the formula v = gt, where g is the acceleration due to gravity and t is the time. Here, g = 20 m/s² and t = 5 s, so v = 20 m/s² * 5 s = 100 m/s.
