Answer:

Gravitational potential energy, E = 297.92 J

Explanation:

Mass of the wheel, m = 38 kg

Height, h = 0.8 m

The gravitational potential energy is said to be possessed by an object due to its height above ground surface. Mathematically, it is given by :

[tex]E=mgh[/tex]

g is the acceleration due to gravity

[tex]E=38\times 9.8\times 0.8[/tex]

E = 297.92 Joules

So, the gravitational potential energy added to the wheel is 297.92 Joules. Hence, this is the required solution.
