Sounds good.

Just remember to include units (I know it's a pain but as a "pseudo-physicist" I had to point it out.). Usually, including units throughout the entire problem is a good way to check if the solution is correct. If the units cancel out as desired, then your solution should be correct (unless you made some silly arithmetic mistake).

Ok thanks, I'll try to do that more often until it becomes second nature. It's not that I don't want to add units but always forget to :rolleyes:

Yeah... I feel you. You'll get used to it after a while.
