The y-coordinate of a particle in curvilinear motion is given by y = 7.5t3 - 7.5t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a, = 2.8t in./sec?. If the velocity of the particle in the x-direction is 5.3 in./sec when t = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 1.6 sec. Construct v and a in your solution. Answers: When t = 1.6 sec, V = in./sec i in./sec? a =
