Question

If a body is moving in a circular path of radius 5m than find the displacement and distance of the body in
1.full cycle
2.half cycle
3.3/4 cycle

Answer 1

1.Displacement will be 0 as there is no distance between the final and initial position of the body
.Distance with be =2× pi×5=10 pi m.
2.Displacement will be equal to the diameter of the circle that is
2×5=10 m.
.Distance will be
1/2×2 pi×5= 5 pi m.
3.Using the pythagoras theorem Displacement =root over of 5 square+5 square ie. =5 root 2 m.
.Distance will be =3/4×2 pi×5 ie. =15/2 pi m.
