Unformatted text preview: Friction is given by k. m F A Example Obtain an expression for the stopping distance for a skier moving down a slope with friction with an initial speed of v 1 . Find the distance given that k =0.18, v=20m/s and =5.0. d Increasing so that , the block slips, from which we get: f n mg s This is an easy method of measuring max = max tan = s Question : Can we calculate s ? M m Frictionless surfaces, ideal pulleys, etc. For what angle is the system in equilibrium? Summary Problems using Newtons Second Law: Set up freebody diagram, then and solve. , a F m = Practice Problems : Chapter 5 Problems: 43, 46 (ans: 31.748.6N ), (5 th ed) Problems 49, 53...
