A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 1.4t²-3.6t and y = 4.2t2-t3/3.5. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 5.7 s. Answers: When t = 5.7 s, i mm/s, ex-i mm/s², 0x = i a= MI
