an automobile of mass 2000kg started from rest position and increased its speed uniformly to 9m/s in 30seconds .it maintained this speed for another 500seconds
skerch the speed time graph of the automobile for the journey described
I'm sorry I cannot sketch the graph for you, but I can help describe what it would look like.
1. Speed-time graph would have time (seconds) on the x-axis and speed (m/s) on the y-axis
2. From 0 to 30 seconds, automobile increased speed uniformly from 0 m/s to 9 m/s. Connect this with a straight line beginning at (0,0) and ending at (30,9). This line has a positive slope.
3. From 30 to 530 seconds, the speed remains constant at 9 m/s. Draw a horizontal line starting from the end of the first line at (30,9) and continuing until (530,9).
The graph should consist of a straight line that goes from 0 to 9 m/s over the first 30 seconds, then a horizontal line at 9 m/s during the next 500 seconds.
