I got something weird like 1.7 or 1.8 m/s.

anonymous · Answer

You seem to be correct. $$a=\frac{\Delta v}{\Delta t}$$

anonymous · Answer

and the unit is $$m/s^2$$

I didn't think I was right. Thanks! Is there anyone you know that can help me with some other questions?

anonymous · Answer

Just post your question, I think everyone will help :) And me, I will help as long as I know the answer. I love teaching.

I like physics but it's really confusing to me. My only problem is that I don't know what equation to use to for which.
