    - In the rectangular co-ordinate system shown above, particle A travels the curved path. The tangential component of velocity is equal to velocity itself.

    - Vx and Vy are the velocity co-ordinates of particle A.

    V = (Vx)i + (Vy) j

    (Vx)i is the horizontal component and (Vy) is the vertical component.

    (Vx) = dx/dt and (Vy) = dy/dt
