Determine the absolute velocity at time t = 2 from the point M, which moves along the diagonal of the rectangular plate 1 according to the law MoM = 0.3t2. The plate itself moves vertically in the plane of the pattern according to the equation s = 1 + 0.5 sin (π / 2) t. The angle α = 45 °. (Answer 0.851)
