Answer:
P.E = 980 Joules
Explanation:
Given the following data;
Mass = 20 kg
Height = 5m
Acceleration due to gravity = 9.8 m/s²
To find the potential energy stored in the block;
Mathematically, potential energy is given by the formula;
![P.E = mgh](https://tex.z-dn.net/?f=%20P.E%20%3D%20mgh)
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 equation, we have;
![P.E = 20 * 9.8 * 5](https://tex.z-dn.net/?f=%20P.E%20%3D%2020%20%2A%209.8%20%2A%205%20)
P.E = 980 Joules
If the object is at equalibirium, then the force is balanced. '<em>Balanced</em>' is the key word that is used to describe equilibrium situations. If the object has a zero net force, the acceleration is 0 m/s/s. Objects at equilibrium should have an acceleration of 0 m/s/s.
I'm not sure. But it can be A or C.
