The mine skip is being hauled to the surface over the curved track by the cable wound around the 36-in. drum, which turns at the constant clockwise speed of 114 rev/min. The shape of the track is designed so that y=x2/49, where x and y are in feet. Calculate the magnitude of the total acceleration of the skip as it reaches a level of 1.8 ft below the top. Neglect the dimensions of the skip compared with those of the path. Recall that the radius of curvature is given by 1+ L d²y dx2 36"
