Question

1/2 * m * v ^ 2 = mgh

Answer 1

C. the square root of 2gh

Explanation:

The square root of 2gh is equivalent to Torricelli's law in the equation.

  given expression:

         $\frac{1}{2}$ m v² = mgh

 to find v, we make it the subject of the expression:

    *multiply both sides of the equation by 2:

             

                     2 x( $\frac{1}{2}$ m v² )= 2 (mgh)

                                      mv²  = 2mgh

    *cancel the mass, m appearing on both sides:

                                    v²  = 2gh

  * find the square root of both side

                                     v = √2gh
