Starting with the three translational equations and the three moment equations for an aircraft derived. Rewrite these equations for a spin-stabilized bullet. Equations are given below: m(U+ QW-VR)= -mgSinφ + FAx+ FPx
m(V+ RU- PW)= mg Cosφ + FAy+ FPy
m(W+ PV-QU)= mgCosφ +FAz+ FPz

a. The bullet is fired along the body y-axis, at pitch attitude angle zero degrees, and is spin stabilized.
b. Do not derive the equations from first principles.
c. Clearly state all of your assumptions.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
