The, including math steps, or you will not get credit! 1. (25 pts.) A block of mass my - 5.000 kg is on an incline of angle A = 40,000 where Ms - 0.450 and /4x - 0.350. This block is connected by a massless string to a hanging mass ma = 12.00 kg by a pulley. The moment of inertia of the pulley is /. As shown in the figure, the string that goes over the pulley is not necessarily in contact with the outer edge of the pulley. Take the distance the string is from the center of the pulley to be ry. Assume the mass on the incline to be moving down the incline. A (a) Based on the information given above, is the pulley massless and frictionless? Very briefly explain. (b) Draw a clear FBD or EBD for each object in the system. You need to know which objects need which type of diagram and how many objects need a diagram. Make sure each FBD or EBD includes all of the required information! (c) If I = 0.025 kg . m' and r1 = 8.000 cm, find the tension(s) in the string and the acceleration of each mass. (d) Is the angular acceleration of the pulley constant? If so, what is it? If not, very briefly explain why it is not constant
