A simple elevator ride can teach you quite a bit about the normal force. There are three different scenarios given detailing the rider's experience in an unnamed hotel. For each scenario, calculate the normal force N,1-3 acting on the rider if his mass is =72.1kg and the acceleration due to gravity =9.81m/s2.

In scenario 1, the elevator has constant velocity. Fn,1=

In scenario 2, the elevator is moving with upward acceleration2=5.51m/s2 Fn,2=

In scenario 3, the cable breaks and the elevator accelerates downward at 3==9.81m/s2 Fn,3=
