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]

Section 4.3 and 4.4 Control Volume and System Representations and the Reynolds Transport Theorem 4.32 Water flows through a duct of square cross section as shown in Fig. P4.32 with a constant, uniform velocity of V = 20 m/s. Consider fluid particles that lie along line A-B at time t = 0. De- termine the position of these particles, denoted by line A'-B', when t = 0.20 s. Use the volume of fluid in the region between lines A-B and A'-B' to determine the flowrate in the duct. Re- peat the problem for fluid particles originally along line C-D and along line E-F.
