Q1. A crate of 30.2- tools rests on a horizontal floor. You exert a regularly increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 319. After that you must reduce your push to 227 to keep it moving at a steady 24.0.

Q2. Points A and B have electric potentials of 224 V and 125 V, correspondingly. When an electron released from rest at point A arrives at point C its kinetic energy is KA. When electron is released from rest at point B, though, its kinetic energy as it reaches point C is KB = 4KA.
