A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 1.5t2 - 5.2t and y = 2.3t2 - t°/5.8. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 1.4 s.
