Sure, let's find the gravitational potential energy of the traffic light.

Given the mass of the traffic light:

[tex]\[ m = 16.8 \, \text{kg} \][/tex]

Given the height above the ground:

[tex]\[ h = 5.5 \, \text{m} \][/tex]

Given the acceleration due to gravity:

[tex]\[ g = 10 \, \frac{\text{m}}{\text{s}^2} \][/tex]

We use the formula for gravitational potential energy:

[tex]\[ E_g = mgh \][/tex]

Plugging in the given values:

[tex]\[ E_g = 16.8 \, \text{kg} \times 10 \, \frac{\text{m}}{\text{s}^2} \times 5.5 \, \text{m} \][/tex]

So, the gravitational potential energy [tex]\( E_g \)[/tex] is:

[tex]\[ E_g = 924 \, \text{J} \][/tex]

Therefore, the traffic light has a gravitational potential energy of 924 Joules.
