Calculate the linear momentum (L) of a motor car wheel which has a radius of gyration (kG) = 450 mm, diameter = 0.8 m and mass = 6.5 kg. The wheel is moving at an angular velocity, o = 4.5 rad/s. A. 7.50 N.s 10.50 N.s В. c 9.08 N.s OD. 11.70 N.s

4. 00 10 cm MA = 100 g m² = 100 g mc = 200 g mp = 200 g The four masses are connected by massless rigid sticks. a.) Locate the center of mass. b.) The object rotates about an axis that passes through the center of mass and is parallel to the z-axis. The constant angular velocity is w = 8 rad/s. Calculate the total kinetic energy of this system.
