Question

please tll me correct answer please
find distance and displacement from AtoA
A to B
AtoC
AtoD
I need distance and displacement please help me ​

Answer 1

Answer:

Step-by-step explanation: The following answer is valid only if you move through the circumference in the clockwise direction.

Let d be distance and s be displacement,

d of A to A = 2πr

s of A to A = 0

d of A to B = 2πr/4 = πr/2

s of A to B = 2r sin (theta /2 ) , which is the formula for chord length

                 =2r sin(45)

                 =$\sqrt{2}$r

d of A to C = 2πr/2=πr

s of A to C = 2r

d of A to D = 2πr(3/4) = 3πr/2

s of A to D = - $\sqrt{2}$r , negative is due to the opposite direction of motion.

Hope that helps!
