Assuming that $=55,r=4m,{}^{}=5ra\frac{d}{s},r^{}=10\frac{m}{s},{}^{}=5ra\frac{d}{s^2},r^{}=10\frac{m}{s^2},$ determine the

magnitude of the position, velocity and acceleration of the end$-$point in both the polar and normal

and tangential coordinate system. Be sure to include appropriate units. Comment on why the

magnitude of the vectors are the same or different. Also comment on why the magnitude of the

individual components of the vector are the same or different. You may want to show the numerical

values directly below the derived equations in your report.
