20.5.3 The decision of the collection (Reshebnik) Kepe

20.5.3. Generalized power of the mechanical system Qφ = -20sinφ, where Qφ in Nm; φ - the generalized coordinate, rad. Determine the angular acceleration cp at a time when the angle cp = 3 rad, if the kinetic energy of the system T = 5 & phi2 + 30 sinφ ?.
