11.3.9
The relative motion of the point M is determined by the equations xr = et, yr = 2 sin t, and the translational translational motion by the equations xe = e-t; Ye = 2 cos t. The axes of the absolute and relative coordinate systems are parallel. Determine the modulus of absolute acceleration of the point M at time t = 0. (Answer 2.83)
