Question

Suppose we represent the distance above the

ground by a positive integer and that below the ground

by a negative integer. An elevator descends into a mine

shaft at 5m per minute. If begins to descend from 15 m

above the ground, what will be its position after

17minutes​

Answer 1

Answer:

Answer. Since downwards is negative, the velocity of the elevator is -5 m/min. ... However, since we started 15 m above ground, displacement from the ground level = -225 + 15 m = -210 m.
