At time t = 17 s, the velocity of a particle moving in the x-y plane is v= 0.14i +2.92j m/s. By time t = 17.13 s, its velocity has become 0.01i + 2.82j m/s. Determine the magnitude aay of its average acceleration during this interval and the angle made by the average acceleration with the positive x-axis. The angle is measured counterclockwise from the positive x-axis.
