Determine the instantaneous acceleration from a velocity-time graph| University Physics

The graph below shows the velocity versus time graph for a certain object. What is the object’s acceleration at time t = 5 s?


ANSWER: 0.0\:m/s^2

The acceleration can be determined from the slope of the velocity-time graph. From the given graph, there is a horizontal line from time 4 seconds to 6 seconds. At this time interval, the velocity is constant. The acceleration at time 5 seconds is therefore 0.
