Question

An object moves in a circular path of radius 14m. Find the distance travelled and displacement if it covers 1.5 rotation.

Answer 1

Explanation:

just take out circumference of the circle which is equal to 2πR and then multiply it by 1.5 as it was rotated 1.5 times.

and for displacement just subtract 1.5×2πR - 2πR that point would be final point

Answer 2

distance is the perimeter plus the half perimeter as it rotates 1.5 times that is 132 m

displacement would be the chord that would be joining the initial point and final point
