A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 4.9t² - 1.6t and y = 4.3t² - 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 = 7.0 s. Answers: When t = 7.0 s, V = 67.71 mm/s, ex= -8.32 15.03 mm/s², 0x= a = i -49.32 M
