20.6.1 The decision of the collection (Reshebnik) Kep O

20.6.1. The kinetic energy of the system T = 0,25 x 12 + 0,25 (x12 + x1x2 + x22). From the differential equations of motion of the system, the corresponding generalized coordinate x2, x2 determine the acceleration at the time when the acceleration x1 = 5 m / s2, and the generalized force Qx2 = 2.5 N.
