The figure shows a reciprocating rectilinear motion model from the Boston Museaum of Science.  A typical use is dispensing fluid from a nozzle (e.g. paint, lubricant, epoxy, etc.) to a product moving down an assembly line.  For clean application the liquid-dispensing nozzle is brought towards the piece at a relatively slow speed, but once the liquid is applied the nozzle is extracted quickly to save time.  Assume the driving wheel has a CONSTANT angular velocity of delta.deltadeltadelta rad/s CW. In the position shown determine the angular velocity and angular acceleration of the slotted arm. Dimensions in mm.
