Answer:

Let the mass of the stone be m which is moving with uniform speed v in a circle of radius r.

The magnitude of velocity is constant but the velocity vector keeps changing its direction at every instant. Hence the linear momentum of the stone changes its direction continuously.

Angular momentum

L

=m(

r

×

v

)=mrv

z

^

Hence the angular momentum is constant in magnitude and always points in z axis.
