A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 1.8t2 -2.1t and y = 4.1t2-t3/1.2. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 3.2 s. Answers: When t = 3.2 s, V= a= mm/s, 0x = i mm/s², 0x= i O
