Figure shows the velocity-time graph of a particle moving in a straight line.
(i) State the nature of motion of particle.
(ii) Find the displacement of particle at t = 6 s.
(iii) Does the particle change its direction of motion?
(iv) Compare the distance travelled by the particle from 0 to 4 s and from 4 s to 6 s.
(v) Find the acceleration from 0 to 4 s and retardation from 4 s to 6 s.
How can you find the following?
Velocity from a displacement – time graph.
A motor car slows down from 72 kmh−1 to 36 kmh−1 over a distance of 25 m. If the brakes are applied with the same force
calculate
- total time in which car comes to rest
- distance travelled by it.
Define 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 ahead at the end of 7th second and by how much?
State whether true or false. If false, correct the statement.
Distance covered by a particle never becomes zero but displacement becomes zero.
Give some examples for vector quantity.
Choose the correct option.
