Homework Statement
Q-Figure shows the acceleration-time graph of a particle moving along a straight line.After what time the particle acquires its initial velocity?The graph is attached.
Homework Equations
We know that change in velocity is equal to the area covered by an acceleration-time graph.
ie (v-u)=at
The Attempt at a Solution
My logic is that the total change in velocity in 2 sec is 3 because (2+1/2*1*2).
So,if again initial velocity is to be reached,then the total change in velocity in negative direction should be 3.However,how should i calculate the time taken?
