Motion in a Plane (2-D Kinematics)

A particle moves in x-y plane according to rule x = asin $\omega$ t and y = acos $\omega$ t. The particle follows

Show answer and solution

Answer: (b)

$x^2 + y^2 = a^2\sin^2\omega t + a^2\cos^2\omega t = a^2$
This is a circle of radius $a$ centred at the origin.
So the answer is (b) a circular path.
