The x component of velocity in an incompressible flow field isgivenbyu=Ax, whereA=2s−1 in meters. The pressure at point ðx, yÞ=ð0,0Þ is p0 =190kPa gage. The density is rho=1 :50kg=m3 and the z axis is vertical. Evaluate the simplestpossibley component of velocity. Calculate the fluid acceleration and determine the pressure gradient at point ðx, yÞ=ð2,1Þ. Find the pressure distribution along the positive x axis.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
