Problem # p017

Relative velocity

The trolley shown is supported by two wheels A and B which allow it to move along on a rod with a velocity v = 20 m/sec to the right.
The circular disk with radius r = 0.2 m rotates on an axle at point D whose bearing are attached to the trolley. The angular velocity of the disk is ω = 35 rad/sec in the counter clockwise direction.
Determine (using the concept of relative velocity) the x- and y-component of the absolute velocity of point E which is located on the perimeter of the disk at the position shown in the figure.
