Homework Help: engineering mechanics

A vehicle on a monorail has a speed S = 10 m/s and an acceleration S=4m/s 2 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 withw=1 rad /s and w=2 rad/s 2 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?

How can there be two values of w at the same time? Is one of those two numbers (1 and 2) an angular acceleration?
