16.2.7
A homogeneous rod of mass m = 3 kg, released from rest, begins to fall, sliding along a rough horizontal plane. For an angle φ = 60o, determine the projection of the acceleration of the center of mass C on the Ax axis, if the normal reaction is N = 18.17 H, and the slip coefficient is f = 0.1. (Answer 0.606)
