To determine the potential energy (PEg) of an object, you need to multiply its mass by the acceleration due to gravity (9.8 m/s^2) and the height above the reference point.
To find the potential energy (PEg) of the cat, you'll first need to determine its mass. Unfortunately, the mass of the cat is not provided in the question. However, we can work with the given information of a 20 N cat.
To find the mass, you'll need to divide the force (20 N) by the acceleration due to gravity (9.8 m/s^2). This will give you the mass of the cat:
Mass = Force / Acceleration due to gravity = 20 N / 9.8 m/s^2
Once you have the mass of the cat, you can calculate the potential energy (PEg) using the following formula:
PEg = Mass * Acceleration due to gravity * Height
Now, let's calculate the potential energy of the cat:
PEg = Mass * 9.8 m/s^2 * 5 m
To determine the kinetic energy (KE) of the cat, we need to know the speed or velocity of the cat, which is not given in the question. Without the velocity, we cannot calculate the kinetic energy.
The total energy of the cat is the sum of its potential energy (PEg) and its kinetic energy (KE). Since we only know the potential energy and not the kinetic energy, we cannot calculate the total energy.
