    Motion of a particle given position vector.

    Is it supposed to look like a spring? And was I correct about the velocity? Thank you for the help.

    Motion of a particle given position vector.

    I took the magnitude of the velocity and got sqrt( sin^2 + cos^2 +1) so sqrt(2) , so it would also be constant. Would the particle just be moving around a circle? How could I prove this? Thanks!
