A particle moves in a straight line with a constant acceleration of 1.8 m/s2for 6s, zero acceleration for the next 5s, and a constant decceleration of 1.42 m/s2for 4s. Knowing that the particle starts from the origin and that its velocity is 20.31 m/s during the zero acceleration time interval . Determine the distance (in meters) travelled by the particle after 10.5 seconds. Round off only on the final answer expressed in three decimal places.
