Question

At time t = 13 s, the velocity of a particle moving in the x-y plane is v=0.05i + 2.54j m/s. By time t = 13.05 s, its velocity has become
-0.12i+2.42j m/s. Determine the magnitude day 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.
