How can I get clarification on a wrong answer in a physics test?

[Joe90]

Hi all.

I'm a beginning high school physics teacher from New Zealand. I've found some answers on these forums which have helped me out a lot over the last few months. Marking a test tonight I came across an answer which is wrong but I'm finding it hard to explain clearly why the attempted method of solution doesn't work. So I joined up so I could ask for some clarification.

Cheers from the bottom of the world.
Joe.

Hi Joe90!

Our physics homework subforum sounds appropriate. [emoji57]
