Question

Answer the following questions. Where appropriate, show your work and list any assumptions. Attach extra pages if needed. What defines a "well-defined system"? A. A system that continually gains particles B. A system that keeps the same number of particles during an interaction O A system that continually loses particles D. A series of particles not defined by any boundaries of space If no external forces are applied on a system of particles, what may be assumed to be true? A. There are non-conservative forces acting on the system B. Energy cannot be conserved C. Momentum is conserved 6 Impulse must be considered when analyzing the system Question 3 (2.5 pts) Which type of motion is best described as the following: the particles on a rigid body move in parallel planes along circles centered on the same fixed axis? A. Curvilinear translation B. Rotation about a fixed axis C. General plane motion D. General motion When considering rotation about a fixed axis, we considered several assumptions when analyzing rigid bodies in contact. In particular, we considered two general cases. Which of the following statements is an incorrect assumption when analyzing rotation about two rigid bodi in contact? A. There is slipping between bodies B. The rigid bodies are in contact Two points are instantaneously in contact D. Due to no slipping, the absolute value of the velocity at the point of contact is eq
