Unformatted text preview: φ that this cable makes with the vertical, the initial velocity v can be found, assuming its mass m is known. Find v , given M , l , φ , and m . Problem 4 A chain of mass m and length L is suspended vertically with its lower end touching a scale. The chain is released and falls onto the scale. What is the reading on the scale as a function of x , where x is the length of chain that has fallen? Problem 5 A man of mass m stands on a railroad car which is rounding a circular curve of radius R at speed v . His center of mass is height L above the car and his feet are a distance d apart. The man is facing the direction of motion. How much weight is on each of his feet? 1...
