The velocity-time graph of the motion of the elevator.
Explanation of Solution
Given Info:
The upward acceleration of the elevator is,
The time for the upward acceleration is,
The constant velocity of the elevator is,
The time for the constant velocity is,
The downward acceleration of the elevator is,
The time for the upward acceleration is,
Formula Used:
The acceleration describes the slope of the velocity-time graph.
Calculation:
The velocity-time graph is given in the figure (1) using the given information. Here the elevator starts at rest from the ground floor of a three-story shopping mall. It is accelerating for 2 second with acceleration of
