Water flows steadily through a horizontal pipe of varying cross section. at one place the pressure 15 1.5 atm and the speed is 1.0 m/sec. determine the pressure at another place where the speed is 10 m/sec.
a. 0.5 atm
b. 0.6 atm
c. 0.7 atm
d. 0.8 atm
e, 1.0 atm

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
