Problem An elevator travels up and down. The vertical position of the elevator in meters over time is shown below. Graph of vertical position x (in meters) on y axis and time (in seconds) on x axis. The initial position is 12 m at t=0 s, and the position is constant until t=8 s. Then the position decreases linearly to 0 m at t=16 s, then decreases linearly (with a sharper slope) to -15 m at t=20 s, then increases linearly to -6 m at t = 24 s.
