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

The value of the total internal energy produced during this process is 450 J.

Explanation:

The expression for the work done in terms of force and displacement is as follows;

W=Fs

Here, W is the work done, F is applied force and s is the displacement.

Calculate the work done.

Put F= 25 N and s= 30 m in the above expression.

W=(25)(30)

W= 750 J

The expression for the work done in terms of the change in the kinetic energy from work energy theorem is as follows;

Here, is the change in the kinetic energy.

Total internal energy= work done - kinetic energy

Put work done= 750 J and kinetic energy= 300 J.

 Total internal energy=750 - 300

                                 = 450 J

The remaining energy will get transformed into internal energy.

Therefore, the value of the total internal energy produced is 450 J.
