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.
Using following data, draw time - displacement graph for a moving object: | Time (s) | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | |---|---|---|---|---|---|---|---|---|---| | Displacement (m) | 0 | 2 | 4 | 4 | 4 | 6 | 4 | 2 | 0 | Use this graph to find average velocity for first 4 s, for next 4 s and for last 6 s.
The slope of the Distance-Time graph and Velocity-Time graph represents:
