A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 1.8t²-3.5t and y = 3.5t2-t3/1.8. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 6.8 s. Answers: When t-6.8 s, V= a- 36.17 i 16.6 mm/s, ex- i -54.5 mm/s², ex-i -77.05
