 DYNAMICS - CASE STUDY Introduction Problem Setup At Studebaker's new Super Auto Showcase, an inexperienced salesperson drives a pickup truck toward the edge of the giant carousel while the carousel is still rotating. Look out! What is known: The carousel has a 15 meter radius and is spinning with a constant angular velocity, ωo, of 0.05 rad/s. The center of mass of the truck is initially 4 meters from the center of the carousel. The truck travels in a radial path across the disk with a velocity of vr(t) = 0.0889t m/s. Problem Diagram Question What are the velocity and acceleration of the truck when its center of mass is 14 meters from the center of the carousel? Approach The motion of the truck can easily be described using polar (radial and transverse) coordinates. The theory section will develop equations for velocity and acceleration in polar coordinates that make it easier to determine the velocity and acceleration of the truck
