Question

An object is placed in freefall from a resting position. If the object falls for 15 seconds, how far does it fall, and how fast is it moving?​

Answer 1

(Isn't answer but use this to help you)

Step-by-step 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.
