Answer: 2934.75 Joules
Explanation:
Potential energy can be defined as energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
<em>P.E = mgh</em>
Where P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per second square.
h represents the height measured in meters.
Given the following data;
Weight =645
Height = 4.55
<em>P.E = mgh</em>
But we know that weight = mg = 645N
Substituting into the equation, we have;
<em>P.E = 645 • 4.55</em>
<em>P.E = 2934.75J</em>
Potential energy, P.E = 2934.75 Joules.
 
        
             
        
        
        
The statements that are held true with regards to the static equilibrium of bodies are:
<span>The net torque acting on the object must equal zero
</span><span>The net torque on the object does not have to be zero if the net force on the object is zero
Furthermore, when a body is in a state of static equilibrium, the summation of all forces, either vertically or horizontally, must be equal to zero. </span>
