I suffer a very similar affliction as a theater major.

Meh, skip movies.  You don't want to throw money at Disney now anyway.

They forgot “girls will never talk to you at parties”. 

 

Meh, that was the case long before I declared a physics major.  It was the case when I stopped going to parties, which was two years plus before I declared major.

Possibly but unlikely.  Oh, and if you need a problem, here's one I gave last week:

Quote

A nucleus of polonium-210 (i.e., it has mass 210 u), initially at rest, disintegrates into three fragments. The first has mass 114 u and moves in the +x direction at 1.00 × 10^4 m/s. The second has mass 92 u and moves at 1.73 × 10^4 m/ s at an angle 154.94° from the motion of the first fragment. The last is an alpha particle (mass 4 u). Find the velocity of the alpha particle, specifying both magnitude and direction.
