I have a few questions...okay lots actually! I am terribly confused and hopefully you can help me!! A car is up on a hydraulic lift at a garage. The wheels are free to rotate, and the drive wheels are rotating with a constant angular velocity. Does a point on the rim of a wheel have a.) a tangential acceleration and b.) a centripetal acceleration? Two points are located on a rigid wheel that is rotating with an increasing angular velocity about a fixed axis, The axis is perpendicular to the wheel at its center. Point 1 is located on the rim, and point 2 is halfway between the rim and the axis. At any given instant which point if either has a greater a) angular velocity b) angular acceleration c) tangential speed d) tangential acceleration and e) centripetal acceleration? A building is locating on the earth's equator. Which has the greatest tangential speed due to the earth's rotation, the top floor, the bottom floor, or neither?
