    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?
