Hi @ozni. As you may know, you have to show evidence of your own work first, before we help.

This is just an exercise in algebra. To get you started:
1) square both sides of your equation for p;
2) get rid of the fraction on the right side: remember ##A = \frac BC## rearranged becomes ##AC = B##;
(You can reverse steps 1 and 2 if you prefer., or combine the steps if your algebra is good enough.)
3) see if you can manipulate what you now have to get an expression for ##v^2##, then take the square root.

Post your working, or as much of it as you can do, here. We prefer you use Latex for equations (see guide in bottom left of edit-window).

Edit: Aha - @Orodruin just beat me to it. But since I've already written my reply, I'll post anyway.

Its funny, I gave this problem to my class today. Perhaps you are a student of mine :)
Not unless they are a *very* remote learning student. Using my Mentor superpowers, you two are posting from opposite sides of the planet. :smile:
