What is the height of a 2.00 kg object if its potential energy is 100 j?

Given that:

       height (h) = ?

       mass  (m) = 2 Kg ,

       Potential energy (P.E.) = 100 J ;

    We know that P.E = m × g × h

                            100 J = 2 × 9.81 × h

                                h = (100) ÷ (2 × 9.81)

                               h  = 5.09 m
