The figure gives the acceleration *a* versus time *t* for a particle moving along an *x* axis. The *a*-axis scale is set by *a _{s}* = 16.0 m/s

Step 1

**Given information:**

Scale a-axis = 16 m/s^{2}.

Velocity at t = -2 s is 10 m/s

Velocity at t = 6 s is?

The change in velocity in a-t graph is given by area under the a-t graph

Step 2

Calculation of area a-t graph

Divide the given graph into 3 segments

From -2 to 0 sec segment-1

From 0 to 4 sec segment -2

From 4 to 6 sec ...
