(d) The required friction force in part (c) is well within design limits. The fastest speed, however, is well below that of current leading rides, so you would like to increase the maximum speed. You can't make the tower taller above ground, so you decide to include a feature where part of the track goes underground. Determine the depth (in m) to which the underground part of the ride must go to increase the maximum speed to 53.0 m/s. Assume the overall length of the first part of the track remains at 230 m and the length of track from the top to the lowest underground point is 150 m. The same 400 N friction force acts on the entire 230 m section of track. m
