Hi, here in this given problem there are two position versus time curve.
00:08
In the first one, position over x -axis, sorry y -axis and time over x -axis.
00:20
Time is being measured in second, position is being measured in meter.
00:25
And the curve is something like this.
00:33
So it must represent that the object is moving with a large speed initially because the slope gives, slope of position time curve gives the speed.
00:48
So we conclude object initially moving with the large speed, then the speed or velocity.
01:13
It goes on decreasing as the slope goes on decreasing means it is under retardation becomes zero here when the slope becomes zero for an instant the velocity becomes zero and then starts increasing again increasing again but in opposite direction for example, an object thrown vertically upwards.
02:33
Now for the second figure, this is the graph again position versus time curve, time over x -axis, position over y -axis, and the curve is something like this...
