As a box is pushed 30 meters across a horizontal floor by a constant horizontal force of 25 newtons, the kinetic energy of the box increases by 300 joules.

How much total internal energy is produced during this process?

Answer:

1,050 Joules

Step-by-step explanation:

Step 1: work done in moving the box 30 meters

work done = force X distance

= 25N X 30 = 750 Joules

Step 2: calculate total internal energy

Total internal energy = work done + kinetic energy

= 750 Joules + 300 Joules

= 1,050 Joules = 1.05 KJ
