The problem describes two phases of motion in perpendicular directions (East and South). The net displacement is the vector sum of the displacements in each phase. Since the displacements are perpendicular, the magnitude of the net displacement can be found using the Pythagorean theorem.
Starting from rest a vehicle accelerates at the rate of 2 m/s2 towards east for 10 s. It then stops suddenly. It then accelerates again at a m/s2 for next 10 s towards south rate of 4 and then again comes to rest. The net displacement of the vehicle from the starting point is
