Four cars A, B, C and D are moving on a levelled road. Their distance versus time graph are shown in the given figure. Choose the correct statement-
Which of the graphs represents uniform linear motion?
A car accelerates uniformly from rest to a speed of 30 m/s in 10 seconds. Draw the velocity-time graph for this motion and calculate the acceleration of the car.
If the car continues to travel at a constant speed for an additional 20 seconds, calculate the total distance covered during the entire motion.
Explain how the distance-time graph for uniform motion differs from that of uniformly accelerated motion.
A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Her displacement–time graph is shown in Fig.8.4. Plot a velocity–time graph for the same.
