a) Water (Densitywater = 1,000 kg/m3) flows through a pipe thatnarrows. At point A it is determined that the water flows with avelocity of VA = 93 m/s. At point B it is determined that the waterflows with a velocity of VB = 193 m/s.What is the nagnitude of thedifference in pressure between points A and B.
b)
Two trains pass each other. Train A is traveling 36 m/s east.Train B is traveling 23 m/s west. After the trains pass each othertrain A blows its whistle with a frequency of 578 Hz. Whatfrequency does a person on train B hear? Assume 342 m/s as thespeed of sound.
c) When a 0.427 kg mass is hung from a certain spring itstretches 0.155 m to its equilibrium position at a point P. If thismass is pulled down 0.11 m from point P and released, what is themagnitude of the maximum acceleration of the mass inm/s2?
d) A pipe with an internal diameter of 2.54 2.66 cm attaches toa hose with an internal diameter of 1.11 1.257 cm. It is determinedthat water flows through the pipe with a velocity of 0.755 0.803m/s. With what velocity does the water flow through the hose?
