Answer :

We know that,


Slope of s-t graph represents acceleration.


y- Coordinate of point on s-t graph represents speed.


From the given s-t graph,


Slope is maximum in interval 2. So, it has maximum average acceleration.


y- Coordinate value of point in interval 3 has highest value thus, interval 3 has maximum average speed.


In interval 1,


Slope is positive. So, acceleration is positive.


y- Coordinate of points are positive. So, speed is positive.


In interval 2,


Slope is negative. So, acceleration is negative.


y- Coordinate of points are positive. So, speed is positive.


In interval 3,


Slope is positive. So, acceleration is positive.


y – Coordinate of points are positive. So, speed is positive.


At A, B and C slopes of curve are ‘0’. Thus, Acceleration at this point are zero.
