A trolley with a mass M = 1000 kg is lowered along a cable railway with an inclination angle a = 30°. Determine the tension in the rope when the trolley is braking at the end of the descent, if the speed at the end of braking is v0 = 5 m/s and the braking time is t0 = 10 s. Take the friction coefficient equal to u = 0.4, the acceleration of free fall g = 10 m/s2.
