Question: What is the total mechanical energy of a system if the potential energy is 50 J and the kinetic energy is 30 J?

Options:

Correct Answer: 80 J

Solution:

Total Mechanical Energy (TME) = Potential Energy + Kinetic Energy = 50 J + 30 J = 80 J.

What is the total mechanical energy of a system if the potential energy is 50 J and the kinetic energy is 30 J?

What is the total mechanical energy of a system if the potential energy is 50 J and the kinetic energy is 30 J?

Step 1: Identify the potential energy of the system, which is given as 50 J.
Step 2: Identify the kinetic energy of the system, which is given as 30 J.
Step 3: Use the formula for total mechanical energy, which is Total Mechanical Energy (TME) = Potential Energy + Kinetic Energy.
Step 4: Substitute the values into the formula: TME = 50 J + 30 J.
Step 5: Calculate the total: 50 J + 30 J = 80 J.
Step 6: Conclude that the total mechanical energy of the system is 80 J.
