Answer:

a) 28m distance and displacement both

b) 88m distance and 0m displacement.

Verified answer

Answer:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

a) Distance = half of circumference of circle = 2πr/2 = πr = 14π m (Solve it further by using π as 22/7) = 44 m

   Displacement = diameter = 2*r = 2r = 2*14 = 28 m

b) Distance = circumference of circle = 2πr = 2*14π = 28π m (Solve it further by using π as 22/7) = 88 m

   Displacement = Its start and finish position are same so no apparent change in position = 0 m
