The rectangular coordinates of a particle which moves with curvilinear motion are given byx= 10.25t+1.00t² -0.25t³ and y=6.10+ 16.04t - 2.29t², 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 28° with the positive x-axis. Answers: V= (6.25 a- (-4 MI 0.227 i+ -2.28 i+ -4.58 S j) mm/s j) mm/s²
