Question
![2/125 The mine skip is being hauled to the surface over
the curved track by the cable wound around the
30-in. drum, which turns at the constant clockwise
speed of 120 rev/min. The shape of the track is de-
signed so that y = x²/40, where x and y are in feet.
Calculate the magnitude of the total acceleration of
the skip as it reaches a level of 2 ft below the top.
Neglect the dimensions of the skip compared with
those of the path. Recall that the radius of curva-
ture is given by
