A trolley weighing 200 kg is lifted along rails up a mountain, the inclination of which to the horizon is 30°. What work (in kJ) was done by the traction force along a path of 50 m, if it is known that the trolley was moving with an acceleration of 0.2 m/s2? Friction coefficient 0.2. g = 10 m/s2. |/ 3 = 1.7.
