Question

calculate the distance and displacement of an object under following conditions:-
1.after half complete rotation in circular motion
2. after one complete rotation
3. after two complete and one half rotation
4. after four complete and two-fourth of one rotation.
5. after one-fourth of a rotation

Answer quickly friends please

Answer 1

1.after half complete rotation in circular motion
Distance & displacement =(πr)
2. after one complete rotation
Distance= (2πr)&displacement =0
3. after two complete and one half rotation
Distance =5πr)&displacement =(πr)
4. after four complete and two-fourth of one rotation
Distance =(9πr)&displacement (πr)
5. after one-fourth of a rotation
Distance & displacement (πr/2)
