Solution

(a) kite flying on a windy day: three dimensional motion
(b) Car on straight highway: one dimensional motion
(c) Insect crawling on a globe: three dimensional motion on a Cartesian coordinate system & two dimensional motion on a spherical polar coordinate system
(d) A carom coin rebounding from the side of the board: One dimensional motion
