Question

1. A winding drum raises a cage through a height of 120 m. The cage has, at first, an
acceleration of 1.5 m/s2 until the velocity of 9 m/s is reached, after which the velocity is
constant until the cage nears the top, when the final retardation is 6 m/s2. Find the time
taken for the cage to reach the top.​

Answer 1

Answer:

A winding drum raises a cage through a height of 120 m. the cage has, at first, an acceleration of 1.5 m/s2 m / s 2 until the velocity of 9 m/s is reached, after which the velocity is constant until the cage nears the top when the final retardation is 6 m/s2 m / s 2 .
