Velocity-dependent acceleration A train traveling at vo= 23.0 m/s begins to brake by applying a velocity-dependent instantaneous acceleration a a(v) = m/s? v + u where a = -21.0 m?/s³, v is the instantaneous velocity of the train, and u=0.6 m/s. Determine the distance D traveled by the train before it comes to a complete stop.

Context The position of a peculiar fish as a function of time is given by the following equation. Time is in seconds, position is in meters, and the positive direction is to the right. x(t) = 2t3 + 12t2 - 72t The fish's position, velocity, and acceleration functions are x = 2t3 + 12t2 - 72t, v = 6t2 + 24t - 72, and a = 12t + 24. Question: When, if ever, is the fish at rest? Drag the appropriate label(s) to the correct location(s) on the number line. Remember that it is the circle in the upper left corner of the label that must be in the correct place. Drag the period (.) to denote a single time; for example, t=0. Drag the left bracket ([) to denote the lower end of a range; for example, t>0. Drag the right bracket (]) to denote the upper end of a range; for example, t<0. Drag "none" anywhere near the line if the fish is never at rest. You may place as many of each symbol on the line as needed. See image attached:
