A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 3.3t²-3.5t and y = 5.2t²-t3/2.1. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 1.9 s. Answers: When t = 1.9 s, V= a = tel mm/s, 0x = i mm/s², 0x = i
