The height of the object above the ground is 10 m.
The given parameters;
- gravitational potential energy of the rock, P.E = 196 J
- mass of the rock, m = 2 kg
- acceleration due to gravity, g = 9.8 m/s²
Potential energy of an object is the energy possessed by an object due to its position.
The height of the object is calculated as follows;
P.E = mgh
where;
h is the height of the object above the ground
[tex]h = \frac{P.E}{mg} \\\\h = \frac{196}{9.8 \times 2} \\\\h = 10 \ m[/tex]
Thus, the height of the object above the ground is 10 m.
