PS - this example is from an phisics's exam.
It still doesn't matter. Please post questions like this where it belongs - in the Homework zone section. Secondly, you should not expect people to answer questions like this point blank. You HAVE to show what you know, what you have attempted, and why you can't do this or where you got stuck (Read the sticky in the Homework section).
