An elevator brimming with tourists has a mass of 1900 kg. The elevator accelerates upward (in the positive direction) from rest at a rate of 1.8 m/s2 for 2.5 s. The elevator continues upward at constant velocity for 8.2 s. The elevator experiences a negative acceleration at a rate of 0.45 m/s2 for 2.1 s.

How far, in meters, has the elevator moved above its original starting point?
