9 The position vector of a particle moving in the x-y plane at time t = 3.60 s is 2.76i 3.28j m. At t = 3.62 s its position vector has become 2.79i- 3.33jm. Determine the magnitude v of its average velocity during this in- terval and the angle 9 made by the average velocity with the x-axis. رفع جك Ans. v 2.92 m/s, 0 2.92 m/s, 0 = - 59.0°
