The diagram for the velocity time graph representing the motion of the car is in the image attached.
How to sketch velocity - time graph?
The velocity time graph is sketched by applying the following method below;
If the car starts from rest, the initial velocity of the car is zero.
If the car later reached 5 m/s in 10 seconds, the final velocity of the car is 5 m/s. And the time of motion of the car is 10 seconds.
The acceleration of the car is calculated as follows;
acceleration = change in velocity / change in time
acceleration = ( 5 m/s - 0 m/s ) / 10 s
acceleration = 0.5 m/s²
Thus, the diagram for the velocity time graph representing the motion of the car is in the image attached.
