Question

A velocity vs. time graph is shown.

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 20. A line starts at the origin and ends at (5, 20).
What is the acceleration of the object?

0 m/s2
0.25 m/s2
4 m/s2
8 m/s2

Answer 1

Acceleration = slope = Δv/Δt = (20 m/s − 0 m/s) / (5 s − 0 s) = 20/5 = 4 m/s².
