The y-coordinate of a particle in curvilinear motion is given by y = 3.1t3 - 9.0t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by ax = 8.0t in./sec². If the velocity of the particle in the x-direction is 5.6 in./sec when t = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 1.1 sec. Construct v and a in your solution. Answers: When t = 1.1 sec, V = a = i i in./sec in./sec²
