A100 kg bag of sand has a weight on 100 n. when dropped its acceleration is what?

Explanation:

If you are holding the bag of sand, the only acceleration in the system is gravity, because is a vertical movement. So,

We are assuming that is vertical movement because is say ''dropped'', which is a term used in Free-fall models, where acceleration is constant.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
