to do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out? input energy? j kinetic energy 400 j friction 150 j heat 250 j 50 j 250 j 400 j 800 j

Answer

Explanation:

Step1: Identify energy - output forms

The truck's output energy is in the form of kinetic energy, heat due to friction.

Step2: Calculate total output energy

The kinetic energy is 400 J, heat due to friction is 250 J and friction loss is 150 J. The total output energy is the sum of kinetic energy and heat energy. So, $400 + 250+150=800$ J.

Answer:

800 J
