A box slides across a frozen pond toward the left shore as two children standing on opposite shores pull on the box with ropes. The child on the left shore pulls with a force of \(3.0 \mathrm{~N}\), and the child on the right shore pulls with a force of \(2.0 \mathrm{~N}\). At a certain instant, the speed of the box is \(3.0 \mathrm{~m} / \mathrm{s}\).

(a) At that instant, what is the power resulting from each force?

(b) What is the power resulting from both forces?

(c) Do your answers to parts \(a\) and \(b\) change as the box slides?
