Question

A child has two red wagons, with the rear one tied to the front by a stretchy rope (a spring). If the child pulls on the front wagon, the energy stored in the system increases. How do the relative amounts of potential and kinetic energy in this system change over time?

Can the work done by Friction be zero? In a case where static friction exists, the object does not move and the change in kinetic energy is also zero? W = Fd = ?KE = 0? What did I do wrong?
Energy conservation with conservative forces: A very small 100-g object is attached to one end of a massless 10-cm rod that is pivoted without friction about the opposite end. The rod is held vertical, with the object at the top, and released, allowing the rod to swing. What is the speed of the object at the instant that the rod is horizontal? 1.8 m/s 1.4 m/s 0.71 m/s 2.8 m/s 4.0 m/s fbb

Two people stand on opposite sides of each other (one on the left and one on the right) pulling on a rope in a game of tug of war. The two people pull on the rope with equal and opposite forces. Which of the following is the expected out come for the work done to the system? No work is done on the rope since the rope has no displacement. Each player does equal amount of non-zero work. The rope moves to the right and the work is positive. The rope moves to the left and the work is negative.
