[Figure: Graph showing accelerometer data for elevator ride with spikes at 10s and 72s]
Shown here is accelerometer data for an elevator ride in a skyscraper in Chicago. The spikes at roughly 10s and 72s are caused by the handling of the accelerometer which rested on the floor of the elevator and occurred before the elevator started moving up, and after it reached the top, respectively. What is the best estimate for the peak vertical speed for this elevator
(A) 4 m/s
(B) 8 m/s
(C) 12 m/s
(D) 16 m/s
(E) 20 m/s
