![A particle moves along the x axis. Its position is given by the equation x = 2.1 + 2.7t - 3.5t²with x in meters and t in seconds.
(a) Determine its position when it changes direction.
2.56
The initial position is 2.1 m, the initial velocity is 2.7 m/s and the acceleration is −2 × 3.5 m/s². Use the constant acceleration equation
(b) Determine its velocity when it returns to the position it had at t = 0? (Indicate the direction of the velocity with the sign of your answ
