Q7) a) Work along a line Find the work done by a force F = 5i (magnitude 5 N) in moving an object along the line from the origin to the point (1, 1) (distance in meters). b) Locomotive The Union Pacific's Big Boy locomotive could pull 6000-ton trains with a tractive effort (pull) of 602,148 N (135,375 lb). At this level of effort, about how much work did Big Boy do on the (approximately straight) 605-km journey from San Francisco to Los Angeles? c) Inclined plane along a loading dock by pulling on it with a 200-N force at an angle of 30° from the horizontal? How much work does it take to slide a crate 20 m d) Sailboat The wind passing over a boat's sail exerted a 1000-lb
