The y-coordinate of a particle in curvilinear motion is given by y = 2.4t³ - 7.3t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a, = 5.7t in./sec2. If the velocity of the particle in the x-direction is 13.9 in./sec when t = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 3.0 sec. Construct v and a in your solution. Answers: Whent = 3.0 sec, v = i in./sec i in./sec2 a =
