NO THE ANSWER MUST BE 0.6 m/s. total displacement = 200+220 cm = 420 cm = 4.2 m total time = 7 sec v= 4.2/7 = 0.6 m/s....

Understanding the Problem
To determine the velocity at the end of the 7th second, we need to analyze the motion of the body over the specified time intervals.
Distance Traveled
- In the first 2 seconds, the body travels 200 cm.
- In the next 5 seconds (from 2 to 7 seconds), it travels 220 cm.
Total Distance and Time
- The total distance traveled in 7 seconds is:
- 200 cm (first 2 seconds) + 220 cm (next 5 seconds) = 420 cm.
- The total time taken is 7 seconds.
Calculating Average Velocity
- The average velocity is calculated using the formula:
- Average Velocity = Total Distance / Total Time
- Average Velocity = 420 cm / 7 seconds = 60 cm/s.
Velocity at the End of 7 Seconds
- Assuming uniform motion, the average velocity can be considered as the velocity at the end of the 7 seconds.
- Therefore, the velocity at the end of the 7th second is 60 cm/s.
Summary
- Distance in the first 2 seconds: 200 cm
- Distance in the next 5 seconds: 220 cm
- Total distance in 7 seconds: 420 cm
- Average velocity: 60 cm/s
This calculation indicates that the body moves with a consistent average velocity of 60 cm/s by the end of the 7th second.
To determine the velocity at the end of the 7th second, we need to analyze the motion of the body over the specified time intervals.
Distance Traveled
- In the first 2 seconds, the body travels 200 cm.
- In the next 5 seconds (from 2 to 7 seconds), it travels 220 cm.
Total Distance and Time
- The total distance traveled in 7 seconds is:
- 200 cm (first 2 seconds) + 220 cm (next 5 seconds) = 420 cm.
- The total time taken is 7 seconds.
Calculating Average Velocity
- The average velocity is calculated using the formula:
- Average Velocity = Total Distance / Total Time
- Average Velocity = 420 cm / 7 seconds = 60 cm/s.
Velocity at the End of 7 Seconds
- Assuming uniform motion, the average velocity can be considered as the velocity at the end of the 7 seconds.
- Therefore, the velocity at the end of the 7th second is 60 cm/s.
Summary
- Distance in the first 2 seconds: 200 cm
- Distance in the next 5 seconds: 220 cm
- Total distance in 7 seconds: 420 cm
- Average velocity: 60 cm/s
This calculation indicates that the body moves with a consistent average velocity of 60 cm/s by the end of the 7th second.
