The rectangular coordinates of a particle which moves with curvilinear motion are given by x = 9.50t + 1.75t² - 0.55t³ and y = 5.99 + 14.37t-2.93t², where x and y are in millimeters and the time t is in seconds, beginning from t = 0. Determine the velocity v and acceleration a of the particle when t = 4 s. Also, determine the first time that the velocity of the particle makes an angle of 23° with the positive x-axis. Answers: v = (i 9.52 a= t= Mi 5.86 it i i+ i S A V j) mm/s j) mm/s²
