A uniform rod of length L and mass 2m is pivoted at the left end, as shown. A point mass m is attached to the rod a distance L/3 from the pivot. Model the mass as a point particle.Find the angular speed of the rod and point particle just as it as fallen to the vertical position.Find the magnitude of the angular acceleration for this system the instant after it is released from rest from the horizontal position in a gravitational field.Find the direction of the angular acceleration for this system the instant after it is released from rest from the horizontal position in a gravitational field.
