Problem: Use the figure below to answer the following question.  The mass of Piston B is 3 kg and the spring has a stiffness of N/m.  Assume that the system is initially at rest and the spring is initially at its free length before being compressed such that m. LO 13b & 13c: On a separate piece of paper, draw a free body diagram using S.P.R.E.A.D. and a kinetic diagram of the piston B. To satisfy the requirements of the quiz, Answer “yes” when complete.

Problem: Use the figure below to answer the following question.  LO 12j: What is the velocity of Boat B with respect to Boat A?  Show your work. Display your response in the format of

Question: Answer the following question. LO 13e: Describe three ways that the normal/tangential coordinate system is different from the rectangular coordinate system when analyzing accelerated motion of a particle using Newton’s 2nd Law.  You may discuss differences in drawing free-body diagrams, kinetic diagrams, or solving problems.
