What is the velocity of an object that has been in free fall for 2.5

Answer: calculate the free fall distance and velocity without air resistance from, the free fall.

Explanation:

To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = - 9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards
