A uniform 3 m ladder of mass 5.00 kg rests against a frictionless vertical wall. The lower end rests on the floor at an angle of 60.0 where the coefficient of static friction is 0.400. A student with a mass of 60.0 kg climbs 0.800 length up the ladder. Will he still remain in equilibrium? 1. Analyze the Leaning Ladder situation, determine the equations that govern the system and solve the problem. Draw a free-body diagram for the Leaning Ladder problem given above. Suppose a different student of mass 73.1 kg climbs up the ladder. How high above the ground could he climb? 2. 3. 4. If the mass remains at 60.0 kg, but the coefficient of friction is only 0.257, how high above the ground can the student climb? 7. What is the minimum angle required for the 60.0 kg student to stand halfway up the ladder for = 0.400 ? l s 5. If a stronger, safer ladder of mass 34.2 kg is used and its coefficient of friction is 0.531, how high above the ground can the student climb? 6. For the 60.0 kg student and friction of 0.400, how high above the ground can the student climb if the angle is cut in half?
