Question

Your company is designing a new water slide. In the initial design, a person travels down a curved slide, ending up moving horizontally at the bottom. There, the person grabs the bottom end of a 16.0 m long vertical bar that is pivoted at its center and swings out over a pool of water. When the bar has swung out as far as it will go, the person lets go and falls down into the water. Your task is to determine the height of the slide so that the maximum horizontal distance that the bar swings out is 5.0 m for a 60 kg person. The mass of the bar is 300 kg. From an engineering handbook, you find that the moment of inertia of the bar is 1/12 of its mass multiplied by its length.
