How high should a box of mass 20kg is lifted to store energy of 10,000 J? (g=10m/s)
1 answer:
Answer:
Height, h = 50 meters.
Explanation:
Given the following data;
Mass = 20kg
Potential energy = 10,000 J
Acceleration due to gravity, g = 10m/s²
To find the height of the box;
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;
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.
Substituting into the formula, we have;
10000 = 20*10*h
10000 = 200h
Height, h = 10000/200
Height, h = 50 meters.
