©Modeling Workshop Project 2006 1 Unit VII ws3b v3.0 Name Date Pd UNIT VII: WS 3b Quantitative Bar Graphs and Problems For each situation shown below : 1. In the energy flow diagram show the system you choose to analyze. Assume the systems to be frictionless unless stated otherwise. 2. Complete the energy bar graph QUANTITATIVELY (numerically accurate). 3. In the space below each diagram use conservation of energy equations to solve for the quantity called for in the question. 1. A moving cart hits a spring, traveling at 5.0 m/s at the time of contact. At the instant the cart is motionless, by how much is the spring compressed? 2. Determine final velocity of the cart, assuming that 10% of the energy is dissipated by friction. 3. A block is placed on a spring, compressing it 0.30m. What height does the block reach when launched by the spring?
