Two particles move along an x axis. the position of particle 1 is given by x ! 6.00t 2 # 3.00t # 2.00 (in meters and seconds); the acceleration of particle 2 is given by a ! "8.00t (in meters per second squared and seconds) and, at t ! 0, its velocity is 20 m/s. when the velocities of the particles match, what is their velocity?
