An object of mass 4 Kg starts at the origin in xy-plane with initial velocityvector,( 0 )1, 1, 1v=<>. A force of magnitude
20 N acts directly upward from the xy-plane underneath the object, while gravitational force acts downward on the object. The magnitude of gravitational acceleration210 m/sg≈. Find, (i) the velocity()vtand the position function ()rtof this object, (ii) the time it lands on ground, and (iii) the coordinates of its landing.
