Question 14 Marks
Instruction: The table given below shows distance (in cm) travelled by the bodies A, B and C. Read this data carefully and answer the questions which follow.
Distance (in cm) covered by different bodies:
Distance (in cm) covered by different bodies:
| Time | Body A | Body B | Body C |
| 1st second | 20 | 20 | 20 |
| 2nd second | 20 | 36 | 60 |
| 3rd second | 20 | 24 | 100 |
| 4th second | 20 | 30 | 140 |
| 5th second | 20 | 48 | 180 |
- Which of the bodies is moving with:
- Constant speed?
- Constant acceleration?
- Which of the bodies covers:
- Maximum distance in 3rd second?
- Minimum distance in 3rd second?
- Which of the bodies is moving with non-uniform acceleration?
Answer
View full question & answer→- Bodies moving:
- The body A is moving with constant speed of 20cm/s.
- The body C is moving with constant acceleration.
$\frac{(60-20)}{1}=\frac{(100-60)}{1}=\frac{(140-100)}{1}=\frac{(180-140)}{1}$
$40=40=40=40$
- Bodies covers:
- Body C covers maximum distance 100cm in 3rd second.
- Body A covers minimum distance in 3rd second.
- Body B is moving with non-uniform acceleration and body C is moving with uniform acceleration.
