A disk of radius R = 0.04 m rotates around point O in the plane of the drawing with an angular velocity ω = 0.5t. A point M with a constant relative velocity vr = 0.3 m / s moves along the rim of the disk. Determine the absolute velocity of point M at time t = 2 s, if angle α = 60 ° (Response 0,339)
