A Velocity vs. time graph is shown
What is the acceleration of the object?

The acceleration of the object will be 4 m/s².Acceleration is determined by the slope of the velocity-time graph.
The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The slope of the velocity-time graph gives acceleration.
[tex]\rm a = \frac{20-0}{5-0} \\\\ a= 4 \ m/s^2[/tex]
Hence the acceleration of the object will be 4 m/s².
