Question

Rearrange the formula for mechanical energy to solve for height:

Answer 1

Explanation:

Given formula:

            ME=$\frac{1}{2}$mv²+mgh

  To make height the subject of the formula, follow the following procedures;

     Subtract $\frac{1}{2}$mv² from both side of equation

 M.E - $\frac{1}{2}$mv² = $\frac{1}{2}$mv² - $\frac{1}{2}$mv²+mgh

                  This gives:

                        M.E - $\frac{1}{2}$mv² = mgh

Multiply both sides of the expression by $\frac{1}{mg}$

  ( M.E -  $\frac{1}{2}$mv² ) x  $\frac{1}{mg}$ =  $\frac{1}{mg}$ x mgh

       h = ( M.E -  $\frac{1}{2}$mv² ) x  $\frac{1}{mg}$
