B. A vehicle on a monorail has a speed S = 10 m/s and an acceleration S=4m/s2 relative to the ground reference XYZ when it reaches point A. Inside the vehicle, a 3 kg mass slides along a rod which at the time of interest is parallel to the X axis. This rod rotates about a vertical axis with w=1 rad /s and w=2 rad/s2 relative to the vehicle at the time of interest. Also at this time, the radial distance d of the mass is .2 m and its radial velocity v = .4 m/s inward. What is the dynamic force on the mass at this instant?
