Problem 4
The semicircular disk has a radius of 0.4 m. At one instant, when 0-60°, it is rotating
counterclockwise at 0-4 rad/s, which is increasing in the same direction at 1 rad/s². Find the
velocity and acceleration of point B at this instant. (Suggestion: Set up relative velocity and
relative acceleration that way you would for a no-slip disk; remember what I told you to memorize
on the first day of class.) (Answer: B = −2.98î - 0.8ĵ m/s, ãB = 2.45î - 5.74ĵ m/s²)
