ANGULAR MOMENTUM 1. A bowling ball has a mass of 5.5 kg and a radius of 12.0 cm. It is released so that it rolls down the alley at a rate of 12 rev/s. Find the magnitude of its angular momentum. * O 2.4 kg.m2/s 1.4 kg.m2/s 3.4 kg. m2/ s 4.4 kg.m2/s2. What is the angular momentum of a 2.8 kg uniform cylindrical grinding wheel of radius 18 cm when rotating at 1500 rpm? b. How much torque is required to stop it in 6.0 s? * O 7.1 kg.m2/s and 3.2 N 4.1 kg.m2/s and 1.2 N 7.1 kg.m2/s and 1.2 N 6.1 kg.m2/s and 1.2 N 3. A small particle of mass 0.20 kg is being whirled in a horizontal circle at the end of a 2.0 m long string at a constant speed of 1.0 m/s. Determine its angular momentum about its axis of rotation. * 0.40 kg.m2/s O 2.40 kg.m2/s 3.40 kg.m2 /s 1.40 kg.m2 /s
