Redesigning a track. The figure below shows a small block that is released on a slope, which then slides through a valley and up onto a plateau and then through a distanced = 2.03 m in a certain time At. The whole track is frictionless, and the height difference Ah = h1 - h2 between the release point and the plateau is 2.41 m. You want to decrease the time through d by 0.0500 s. What should the value of Ah then be
