How fast will an object be traveling in free fall after a duration of 3 seconds?

29.4 m/s
9.8 m/s
0 m/s
19.6 m/s

The correct answer is: 29.4 m/s

In free fall, an object accelerates towards the Earth due to gravity, which has an approximate acceleration of 9.8 m/s². This means that for every second the object falls, its velocity increases by about 9.8 m/s. After 3 seconds of free fall, you can calculate the velocity by multiplying the acceleration due to gravity by the time in seconds. Specifically, it would be: Velocity = acceleration × time Velocity = 9.8 m/s² × 3 s = 29.4 m/s Thus, after falling for 3 seconds, the object would be traveling at a velocity of 29.4 m/s. This value represents the speed of the object just before it impacts a surface, assuming there is no air resistance acting on it.
