Answer:
P.E = 2934.75
Explanation:
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
[tex] P.E = mgh[/tex]
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 seconds square.
h represents the height measured in meters.
Given the following data;
Weight =645
Height = 4.55
[tex] P.E = mgh[/tex]
But we know that weight = mg = 645N
Substituting into the equation, we have;
[tex] P.E = 645 * 4.55 [/tex]
[tex] P.E = 2934.75 J[/tex]
Potential energy, P.E = 2934.75 Joules.
