Determine the position, the velo and the leration of the particle when t = 1s. 2. The motion of a particle is defined by the relation x = 2t3 – 9t2 + 12t + 10, where x and t are expressed in feet and seconds, respectively. Determine the time, the position, and the acceleration of the particle when v = 0. 3. A loaded railroad car is rolling at a constant velocity when it couples with a spring and dashpot bumper system. After the coupling, the motion of the car is defined by the relation x = 60e-4.8t sin 16t, where x andt are expressed in millimeters and seconds, respectively. Determine the position, the velocity, and the acceleration of the railroad car when (a) t = 0, (b) t = 0.3 s. Vo The motion of a particle is defined by the relation x = 6t* – 2t – 12t2 + 3t + 3, where x andtare expressed in meters and seconds, respectively. Determine the time, the position, and the velocity when a = 0. 12
