The y-coordinate of a particle in curvilinear motion is given by y=12.6t³-13.8t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a, = 9.1t in/sec². If the velocity of the particle in the x-direction is 11.4 in/sec when t=0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 3.9 sec. Construct v and a in your solution. Answers: Whent 3.9 sec. ya in/sec in/sec²
