Question

please answer my 33 question ​

Answer 1

Answer:

(I) distance -2πr

displacement -0

(II) distance -πr

displacement -d

(III) distance -3/2πr

displacement -πr/2

Answer 2

Answer:

A) Distance covered= Circumference of the circle

Distance covered=2πr (from A to A)

• Displacement = 0 because final and initial positions are same..

B) Distance covered = 1/2 of circumference of circle

Distance covered= 1/2 × 2πr

= πr (from a to B )

• Displacement = AB is equal to diameter of the circle

2r or AB

C) Distance covered= 3/4 of circumference of the circle

Distance covered= 3/4× 2πr

3πr/2
