I just wanted to check if i have done this correctlly

I am trying to combine and rearrange the 2 equations to make v the subject.

Please see the attached image.

Have i got this correct?

Brilliant

Thanks Dick

I wasnt too sure about the 2x on the right hand side then finding the square root of the total. but if its ok I am pleased with that.

Hi guys

I have calculated the following equation but i need to find a way of testing it.

the info i was given is a diver at 3.7 m height and I need to find the speed at which they enter the water of the pool. Gravity = 9.8 m s-2.

How do i go about testing the equation to see if i have the right answer?
