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 1.50 × 10 2kg, what is the acceleration of the cage?

a = F/m = 60 / 150 = 6/15 = 2/5 = 0.40 m/s^2
almost half a g, wow !
Gavin wants a cage for his new gerbil, Gary. He found that Gary was 4 3/4 inches from his the tip of his nose to the tip of his tail. Gavin's mom said they would get a larger cage when Gary reached 6 inches. How many more inches does Gary need to grow before Gavin needs to buy a new cage?
