Pulley System Practice A B The system above consists of two masses, A and B, connected by a rope through a frictionless pulley and resting on a frictionless surface. Solve the following problems. 1. Derive an equation for the acceleration of the system. 2. The mass of block A is 15 kg and the mass of block B is 20 kg. Calculate the acceleration of the system. What is the tension in the rope? 3. Calculate the acceleration of the system if the mass of block A is 35 kg and the mass of block B is 50 kg. 4. Calculate the acceleration of the system is the mass of block A is 50 kg and the mass of block B is 35 kg. CHA B A block of mass C is added to the system and attached to block A. Solve the following problems. 5. Determine the acceleration of the system if the masses of blocks A and C are each 17.5 kg and the mass of block B is 50 kg. How does this acceleration compare to your answer for question 3? What can you infer about the two systems? 6. What is the tension in the rope between blocks A and B? What is the tension in the rope between blocks A and C? How do these tensions compare?
