Question

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

For work \(W\), kinetic energy \(K\), and internal energy \(Q\), we have the following. \[W = K + Q\]The relationship between Work, force \(\vec F\), and displacement \(\Delta \vec x\) is as follows.\[W = \vec F \cdot \Delta \vec x\]
