Determine the work of lifting a load along an inclined plane, the average power and efficiency of the lifting device, if the mass of the load is 100 kg, the length of the inclined plane is 2 m, its angle of inclination to the horizon is 30°, the coefficient of friction is 0.1, the acceleration during lifting is 1 m/s2. At the base of the inclined plane the load was at rest.
