A person is pulling on a rope attached to a locomotive of mass m = 100 tons (Fig. 1, right). The person is pulling with a constant force F that is 2 times greater than their body weight, at an upward angle 0 = 30 from the horizontal. The person's mass is 75 kg, and they moved the train by 1 m. Neglecting any friction on wheels and assuming the train was initially stationary, find the speed of the train v at the end of the pull. Assume g = 9.8 m/s. y FA (137 FB Fc B = ? X OOO 30 F
