A wooden stick and a wooden cube each have a small piece of iron embedded in them. We use an electromagnet to exert the same, constant force F on that piece of iron, over a distance d. F is to the right, and large enough that friction is negligible. We don't know the masses. m, is the mass of the cube; m, is the mass of the stick. v is the (linear) speed of the cube. v, is the speed of the stick (that is, the speed of its center of mass); w, and I, are its angular velocity and moment of inertia around its center of mass. If the same force Facts on each piece of iron over the same distance d, which of the following must be true? A. B. C. D. E. mv W s OA O B O c O D O E 17 Don't worry about the electromagnetism, pt. 2 Same situation as the last question. Which of the following must also be true? A. v > V B. v = US C. V mus E. mv = mus F. None of of the above must be true
