What is the total energy of a system with KE = 1368 J and a PE = 5782J? Express your answer in kJ.

Answer:

7.150 KJ

Explanation:

The total energy of a system is the sum of the potential and kinetic energy in the system. According to this question, the kinetic energy (KE) = 1368 J and a potential energy (PE) = 5782J.

Total energy of the system will be PE + KE as follows;

1368J + 5782J

= 7150J

However, the question demanded that the answer be in kJ (kilojoules), which is higher than the joules.

Since 1kJ = 1000J

7150J = 7150/1000

= 7.150kJ
