5. a particle starts from the origin at t=0 with an initial velocity having an xcomponent
of 20 m/s and a ycomponent of 15 m/s. the particle moves in the ryplane with an
component of acceleration only, given by a.- 4.0 m/s2. (a) determine the components
of the velocity vector at any time and the total velocity vector at any time. (b) calculate
the velocity and speed of the particle at 150 s. determine the rand coordinates of the
particle at any time fand the position vector at this time
