The graph below represents the relationship between speed and time for a car moving in a straight line.
What is the acceleration of the car?
a
0 m/s2
b
1.0 m/s2
c
10 m/s2
d
0.10 m/s2
The correct answer is 0 m/s2.
Acceleration is defined as the rate of change of velocity with respect to time. From the graph, we can see that the speed of the car remains constant over time. Therefore, there is no change in velocity and therefore no acceleration.
