Energy stored or conserved in an object is known as potential energy. The position, arrangement, or state of the object or substance determines how much energy is stored.

Potential energy PE = mgh

Where, the mass in kilograms is denoted by m, the acceleration due to gravity is denoted by the letter g. and the height in meters is denoted by h.


Step 1: Find the gravitational potential energy.  

Person mass m = 60 kg

Height of the building = 74.8 m

Acceleration due to gravity   g = 9.8 m/s^2   

Gravitational potential energy, PE = mgh  

PE = 60 * 9.8 * 74.8

PE = 43982.4 joules

Thus, gravitational potential energy PE = 43982.4 joules
