Calculating Velocity at the End of 7 Seconds
- First calculate the total distance covered by the body in 7 seconds:
- Distance covered in the first 2 seconds = 200 cm
- Distance covered in the next 5 seconds = 220 cm
- Total distance covered = 200 cm + 220 cm = 420 cm
- Now calculate the average velocity over the first 2 seconds:
- Average velocity = Total distance / Total time
- Average velocity = 200 cm / 2 s = 100 cm/s
- Next, calculate the average velocity over the next 5 seconds:
- Average velocity = Total distance / Total time
- Average velocity = 220 cm / 5 s = 44 cm/s
- Now, calculate the final velocity at the end of 7 seconds:
- Final velocity = Total distance / Total time
- Final velocity = 420 cm / 7 s = 60 cm/s

Conclusion:
- Therefore, the velocity of the body at the end of 7 seconds from the start is 60 cm/s.
