The vertical motion of an elevator is recorded and a Position vs Time plot is generated. The plot is shown below.
1. Construct a scale drawing of the associated Velocity vs Time plot complete with axis labels.
2. Calculate the average acceleration for the time interval t =8.0s to t = 10s.
3. Sketch a force diagram of an elevator occupant with a mass of 70 kg during the time interval t =8.0s to t = 10s.
4. Calculate the Normal force F N of the occupant using the acceleration you calculated in part 2
5. Write an equation describing the stretch of the steel elevator calbe assuming the cable has a diameter of 8.00mm. Suppose the elevator and ocupants have a combined mass of 450kg.
