Question
The speed of a car at various time stamps are given in the table below. In which of the time interval(s) is the motion of the car uniform?
Hint:
- For a uniform motion, the body has to cover an equal distance in equal time intervals.
- If a body changes its speed over an interval then it can be interpreted that it will cover equal distances in the particular time interval.
The correct answer is: 12:30 to 01:00
- The car attains the max speed of 20
in 30 min which also shows us that the car had to cover different distances in the first ten minutes and different in the next 10 min i.e. from 12:00 to12:30.
- Also while decreasing the speed it again changes the speed and again covers different distances from 1:00 to 1:30.
- This shows that the car was covering a different distance in equal time intervals.
- The car has a uniform motion from 12.30 to 1.00.
in 30 min which also shows us that the car had to cover different distances in the first ten minutes and different in the next 10 min i.e. from 12:00 to12:30.Related Questions to study
