What information about the motion of a body are obtained from the displacement-time graph?
Figure ahead represents the displacement - time sketch of motion of two cars A and B . Find :
(i) the distance by which the car B was initially ahead of car A.
(ii) the velocities of car A and car B.
(iii) the time in which car A catches car B.
(iv) the distance from start when the car A will catch the car B.
A body starts from rest with uniform acceleration 2 m s-2. Find the distance covered by the body in 2 s.
A body starts with an initial velocity of 10m s-1 and acceleration 5 m s-2. Find the distance covered by it in 5 s.
A racehorse runs straight towards the north and covers 540 m in one minute. Calculate
- displacement of the horse,
- its velocity in (a) ms−1 (b) kmh−1.
A satellite makes a complete round along its circular orbit. What is its displacement?
The table below shows the distance travelled by two vehicles A and B during each second:
| Time (s) | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Distance travelled by A (m) | 0 | 20 | 80 | 180 | 240 | 300 | 360 | 420 |
| Distance travelled by B (m) | 0 | 10 | 40 | 90 | 160 | 250 | 360 | 490 |
Which vehicle is moving with a constant acceleration?
A body moves is a circle of radius ‘2R’ what is the distance covered and displacement of the body after 2 complete rounds?
Write a note on the following:
Nautical mile
Using the 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 the first 4 s, for the next 4 s and for the last 6 s.
