Question

Use the information from the graph to answer the question.

A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 12, velocity in meters per second on the y axis, numbered 0 to 45. A line starts at (0, 40) and ends at (12, 10).

What is the acceleration of the object?

m/s2

Answer 1

Acceleration = change in velocity / change in time = (10 − 40) / (12 − 0) = −30 / 12 = −2.5 m/s².
