The value of gravitational acceleration of a body on earth is 9.8 meters/second2. the gravitational potential energy for a 1.00 kilogram object is found to be 12.5 joules. how high is this object above the ground level, where pe = 0? a. 1.3 meters b. 3.5 meters c. 2.0 meters d. 5.6 meters e. 7.9 meters

Given data

Gravitational acceleration           (g) = 9.8 m/s² ,

Gravitational potential energy (P.E) = 12.5 Joules,

Mass of the body                        (m) = 1 kg,

Determine,

Height of the object above the ground level  (h) = ?

We know that,

                the gravitational potential energy is defined as "the energy of an object possesses because of its position in a gravitational field".

Mathematically ,

                         P.E. = m.g.h Joules

                         => h = P.E/m.g   meters

                                 = 12.5 J/ (1 kg×9.8 m/s²)

                                 = 1.275 m ≅ 1.3 m

Therefore, the height (h) of the object above the ground is 1.3 meters.
