Answer:
Explanation:
Time taken to complete one revolutio is 4 min
Revolution completed in one min =|/4
Revolution completed in 6 min =6/4
The body will stop at the ending point of the semicircle
So the displacement will be 2r
Circumference =176
2πr=176
R= 176×7/22×2
R=28m
Displacement=2r =2×28
56m
Hope it helps you.....
