Experimental data indicate that in a region downstream of a given louvered
supply vent the velocity of the emitted air is defined by 0 v vx = 0.18 / ,
where v and x are expressed in m/s and meters, respectively, and 0 v is the
initial discharge velocity of the air. For 0 v = 3.6 m/s, determine (a) the
acceleration of the air at x = 2 m, (b) the time required for the air to flowfrom x =1 to x = 3 m.
