Answer:
The path travelled by a body is called distance. Displacement is the shortest distance between initial and final points.
2πr = 176
⇒ 2 × 22 / 7 × r = 176
r = 28 m
After 6 min, the body would have covered rounds.
Hence if it begins its motion from A, it will reach fill B after 6 min.
Total displacement after 6 min
= AB = 28 x 2 = 56 m

Answer:
0
Explanation:
- draft a circle
- here 176m = 4 min
- so 8 min = so three rounds of four
- since the final and initial point is the same the displacement of the body after 8 mins is = 0
