Question

To do work, this truck uses energy stored in chemical fuel and an electrical battery.

An illustration of truck with a wide arrow away from it labeled input energy? J and it splits into 3 arrows labeled kinetic energy 400 J, heat 250 J, and friction 150 J.
How much total energy does this truck put out?

A. 50 J
B. 250 J
C. 400 J
D. 800 J

Answer 1

Step-by-step explanation:

800 J

Step-by-step explanation:

To do work, this truck uses energy stored in chemical fuel and an electrical battery.

How much total energy does this truck put out?

50 J

250 J

400 J

800 J

Because all you have to do to find initial energy is add up all the energy that was was used up in different forms.

Kinetic Energy 400 J

Heat Energy 250 J

Friction Energy 150 J

Total Initial Energy 800 J
