Lab 5 Post-Lab Questions Question Post-1: You place a 55.0 kg box on a track that makes an angle of 28.0 degrees with the horizontal. The coefficient of static friction between the box and the inclined plane is 0.680. a) Determine the static frictional force which holds the box in place. b) You slowly raise one end of the track, slowly increasing the incline of the angle. Determine the maximum angle that the incline can make with the horizontal so that the box just remains at rest. 89 Lab 5: Variable Forces and Frictionc) With the plane now inclined at this angle, what will the box do if it is given a slight push down the incline? Question Post-2: Your lab partner wears a new pair of sneakers to lab and, rather than performing the required experiments, you decide to measure the coefficient of static friction they make with the lab floor. Your partner reports her mass to be 59.0 kg. Hooking up an industrial force sensor to your interface, you give your partner a piece of rope attached to the sensor and begin to pull. When the sensor reads 318.3 N, your partner starts to slip. a) Determine the coefficient of static friction between your partner and the floor. b) What happens to the force sensor reading just after your partner begins to slip? Does it increase, decrease, or stay the same? Sketch a graph of the applied force over time, starting from right before your partner begins to slip to right after
