A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 1.5t² -2.3t and y = 4.8t2 - t3/5.9. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 5.0 s. Answers: When t = 5.0 s, V = a = i i mm/s, 0x = i mm/s², ex = i
