Question

the angular displacemnt of a particle moving along a circular path of radius r is 9pie/2 rad . the displacemnt of the particle is​

Answer 1

Answer:

√(2) r

Explanation:

9π/2 rad = 810° = 2 1/4 circle

since we are calculating displacement we will take only the 1/4 (90° )

for finding displacement

hypotenuse^2(displacement)= r^2 + r^2

=> displacement^2 = 2r^2

=> displacement = √(2r^2) =√(2) r
