Extracted text: 11.1 The motion of a particle is defined by the relation x = 1.5 - 301 + 5t + 10, where x and t are expressed in meters and sec- onds, respectively. Determine the position, the velocity, and the acceleration of the particle when t = 4 s. 11.2 The motion of a particle is defined by the relation x = 121 18 + 21 + 5, wlhere x and t are expressed in meters and sec- onds, respectively. Determine the position and the velocity when the acceleration of the particle is equal to zero. 11.3 The motion of a particle is defined by the relation x -- 30t + Sx, where x and t are expressed in feet and seconds, respectively. Determine the time, the position, and the accelera- tion when o = 0.
