experimental data indicate that in a region downstream of a given louvered supply vent the velocity of the emitted air is defined by v=0.18 where v and x are expressed in m/s and meters respec-tively and v0 is the intial discharge velocity of the air for v0=3.6m/s,determine(a)the acceleration of the air at x=2m,(b)the time required for the air to flow from x=1 x=3m
