Physics

When an object falls freely in a vacuum, it experiences a constant acceleration due to gravity, which is approximately 9.8 m/s². The velocity of the object at any given time during free fall can be calculated using the equation Vf = Vi + a * t, where Vf is the final velocity, Vi is the initial velocity (which is 0 m/s because the object is in free fall), a is the acceleration due to gravity, and t is the time elapsed.

In this case, t...
