Aparticle moves along the x axis. it is initially at the position 0.270 m, moving with velocity 0.140 m/s and acceleration 20.320 m/s2. suppose it moves as a particle under constant acceleration for 4.50 s. find (a) its position and (b) its velocity at the end of this time interval. next, assume it moves as a particle in simple harmonic motion for 4.50 s and x 5 0 is its equilibrium position. find (c) its position and (d) its velocity at the end of this time interval.
