Full Solution Problem for Chapter 06 (FS06)-Using Generalized Momentum-Impulse equation driving 20 m/s when it sees a deer (at rest in the road). The driver of the car hits the brakes, but it's too late- he hits the deer. The deer sticks to the car (sorry, deerl) and they skid forward as the car br has a mass of 500 kg and the deer has a mass between the car's tires and the road is 0.&. (Friction is much smaller than other forces Find the distance that the car skids of 100 kg. When the brakes are engaged, the coefficient of friction Sketch and translate Sketch the initial and final states and include appropriate coordinate axes. Label the sketches with the known information and identify the unknowns. Decide on the object of reference, Tp: Consider three states Gust before collisin, immediately after and once car has stopped). Choose a system based on the quantity you are interested in, for example, a multi-object isolated system to determine the velocity of an object, or a single-object non-isolated system to determine an impulse or force. Sometimes it is better to decide what is in your systenm and then identify initial and final states Simplify and diagranm . Determine if there are any external impulses exerted on the system. Drawing a force diagram could help determine the external forces and their directions. . Draw an impulse-momentum bar chart for the system for the chosen direction(s) to help you understand the situation, formulate a mathematical representation of the process, and evaluate your results Bar chart (before & after collision) Pin PJP+P Force diagram (after collision Represent mathematically Use the bar chart to apply the generalized impulse-momentum principle along the chosen axis. Each nonzero bar becomesa nonzero term in the equation. The orientation of the bar determines the sign in front of the corresponding term in the equation. Remember that momentum and impulse are vector quantities, so include the plus or minus signs of the components based on the chosen coordinate system. Newton's second law may be needed, too. Solve and evaluate Insert the known information to determine the unknown quantity Check if your answer is reasonable with respect to sign, unit, and magnitude. Also make sure it applies for limiting cases, such as objects of very small or very large mass.
