Say a missile (whatever kind you want) has a velocity of mach 3 if fired from the ground. It's on a plane traveling at mach 1. The pilot fires the missile, it leaves the plane at mach 4.
Correct?
Exactly. BTW, our understanding of these low-velocity situations is due to Isaac Newton, a genius who at the end of his life cited lifelong celibacy as his greatest accomplishment! (Einstein gave us understanding of high-velocity cases, i.e. near speed of light, and I'm not sure to what extent he share'd Newton's views on the merits of celibacy.)
Regarding the effects of panning, assuming you pan the camera at an even rate to match the apparent motion of the bike, I think you'd effectively return to the axle frame of reference in which all parts of the bike are motionless except for the tire, all points of which are moving at the same speed. So I'd expect uniform motion blur on the tire and no motion blur on the rest of the bike in a perfect pan.
