A 0.1-kg particle has an initial velocity at time t1 = 0 [s] in the positive r-direction shown in the figure, and is subsequently acted upon by an external impulse. At time t2 = 0.75 [s], the particle has velocity vz in the direction shown. (Note: the figure indicates the directions of the velocities but not their relative magnitudes.) According to the coordinate system shown (where +x is to the right and +y is upward), select which total (net) impulse I, could have acted on the particle during the time interval t1 < t < t2. O I, = -3j [N•s] O I, = 3j [N•s] O I, = -3i [N•s] O I, = 3i [N•s]
