11.3.11
The point M moves with the acceleration a = 0.4 m / s2 along the rod AB of the hinged parallelogram OABO1. Determine the modulus of absolute acceleration of the point M at the time when the angle φ = 0.5π, the angular velocity of the rod OA 0.1 m in length is ω = 4 rad / s, and the angular acceleration ε = 0.4 rad / s2. (Answer 1.64)
