Two 1.2-lb thrusters on the nonrotating satellite are simultaneously fired as shown. Compute the moment associated with this couple and state about which satellite axes rotations will begin to occur.
a) 1.44 lb-ft, about the z-axis
b) 1.44 lb-ft, about the y-axis
c) 2.88 lb-ft, about the z-axis
d) 2.88 lb-ft, about the x-axis
