The y-coordinate of a particle in curvilinear motion is given by y = 7.2t3 - 10.1t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by ax = 2.7t in./sec2. If the velocity of the particle in the x-direction is 12.1 in./sec whent = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 2.8 sec. Construct v and a in your solution.
