Learning Objectives and Science Practices
- 3.A.1.1 Express the motion of an object using narrative, mathematical, and graphical representations. [SP 1.5, 2.1, 2.2]
- 4.A.2.1 Make predictions about the motion of a system based on the fact that acceleration is equal to the change in velocity per unit time, and velocity is equal to the change in position per unit time. [SP 6.4]
- 4.A.2.3 Create mathematical models and analyze graphical relationships for acceleration, velocity, and position of the center of mass of a system and use them to calculate properties of the motion of the center of mass of a system. [SP 1.4, 2.2]

Setup
A student of mass m stands on a platform scale in an elevator in a tall building. The positive direction for all vector quantities is upward. The vertical position of an elevator as a function of time is shown below. The velocity at 6 seconds is -30 m/s.
Questions
(a) On the grid below, plot the velocity of the elevator as a function of time.
(b) Calculate the average acceleration for the time period t = 2s to t = 4s.
Setup
An inspector provides the student with the following graph showing the acceleration (a) of the elevator as a function of time (t).
Questions
(c) During what time interval(s) is the speed of the elevator constant? How do you know?Β
