The graph represents velocity over time.

a graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). a line runs from 0 seconds 2 meters to 100 seconds 22 meters.

what is the acceleration?

–0.4 m/s2
–0.2 m/s2
0.2 m/s2
0.4 m/s2

Acceleration is 0.2 m/s².

Explanation:

From the graph below,

The x axis represents the time and the y axis represents the velocity.

Now, acceleration of an object is given as:

Acceleration,

Now, from the below graph,

Change in velocity is,

Time interval is,

Therefore, .

Acceleration is 0.2 m/s².

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
