Calculations and Concepts Using Freebody Diagrams A type of elevator called a cage is used to raise and lower miners in a mine shaft. Suppose the
cage carries a group of miners down the shaft. If the unbalanced force on the cage is 60.0 N, and
the mass of the loaded cage is 1.5 x 102kg, what is the acceleration on the cage?
Miners do not like using the cage, so they walk down stairs to enter the mine
