I know that the motion is non-uniform, but I am not quite sure how to solve for the average speed.

Answer 1

Ans

The average speed between t = 4s to t = 6s = (distance travelled)/ (time interval)

From the graph, the distance traveled = 5.5 m(( assuming the scale is 1m)

and time interval = 6- 4 = 2 s

The average speed = 5.5/2 = 2.75 m/s
