Consider a person holding a vacuum cleaner (idealized as Bar AB). The point where the person holds the handle (point A) is constrained to move along the vertical and has a velocity of 0.12 m/s downwards and is increasing its speed at a constant rate of 0.4 m/s2. This is to move the tail end (Point B) of the cleaner. The tail end of the cleaner has a velocity of 0.0840 m/s to the right and the vacuum cleaner has an angular velocity of 0.0586 rad/s.a) What is the the magnitude of the angular acceleration of the vacuum cleaner (Bar AB)? (1.313, 3.5, 0.875, 1.969)
b) What is the magnitude of the acceleration of block B? (0.521, 0.270, 0.1929)
