Q5/ The x-coordinate of a particle in curvilinear motion is given by x = 2t2 - 3t where x is in meters and t is in seconds. Also, the particle has an acceleration in the y-direction given by ay = 8- . If the velocity of the particle in the y-direction is 3 m/sec when t=0, calculate the magnitudes of the velocity v and acceleration a of the particle when t=2 sec, and the angles these vectors make with the x-axis at the same instant. sec2
