The mass of Tesla Model S is 2000 kg and its engine produces 400 Nm of torque. The Mercedes-Benz S Class is 50% heavier, (MBenz= 1.5·MTesla)and the Benz engine produces 50% more torque than the Tesla. For this problem we consider those cars as solid cylinders of the same radius, rolling down the road. What is the ratio of power generated by the engines 6 seconds after a start from rest? (ratio = Tesla Model S/Benz S Class) a) 1/2 b) 2/3 c) 1 d) 3/2 e) 9/4

Two hangers are attached by a string to a vertically mounted pulley system as shown. One disk is bigger than the other, and the disks are attached to each other such that they rotate together. The axle has negligible friction. The mass of the large disk is 1200 grams and the radius is 11 cm. The mass of the small disk is 400 grams and the radius is 4 cm. The high hanger has a mass of 200 grams and starts 80 cm above the ground. The lower mass starts on the ground and has a mass of 100 grams. The hangers are released from rest. What is the velocity of the 200 gram hanger when it hits the floor?
