Answer:

i) So to find the position of the object at time 20 seconds, we draw a line parallel to the y-axis from time 20 and take the point where it intersects then again draw a line parallel to the x-axis, we get the distance where it intersects the y-axis.

Here the position is 8 meters from starting.

ii) Distance travel in 12 seconds by the object is 6 meters.

iii) Since the average speed of an object is defined as the total distance covered by the object by the total time taken. So here total distance is 8 m and the total time is 20 seconds,

Average speed =

= 0.4 m/s

Explanation:

Explanation:

I)nature of the motion is uniform accelaration

ii)slope of graph = 20-8/40-16=12/24=1/2m/s²

III)336 m
