Question

A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, Velocity in meters per second on the y axis, numbered 0 to 25. A line labeled A starts at the origin and ends at (1, 15). A line labeled B starts at (1, 15) and ends at (2, 20). A line labeled C starts at (2, 20) and ends at (4, 20). A line labeled D starts at (4, 20) and ends at (5, 0).on the x axis, numbered 0 to 5, Velocity in meters per second on the y axis, numbered 0 to 25. A line labeled A starts at the origin and ends at (1, 15). A line labeled B starts at (1, 15) and ends at (2, 20). A line labeled C starts at (2, 20) and ends at (4, 20).
The acceleration of segment D is
m/s2.



Rank segments A, B, and C from least acceleration to greatest acceleration.

Least







Greatest

Answer 1

Acceleration of segment D = (0 − 20)/(5 − 4) = −20 m/s².

Accelerations:
- A: (15 − 0)/(1 − 0) = 15 m/s²
- B: (20 − 15)/(2 − 1) = 5 m/s²
- C: (20 − 20)/(4 − 2) = 0 m/s²

Rank least to greatest: C, B, A.
