Full derivation of the projectile motion equations Acceleration is defined as the rate of change of velocity. So, by definition... dv a= dt For the projectile motion case, acceleration is constant. ... To undo differentiation, you need to integrate. ... The right hand is just the integral of the differential of v - i.e. it takes you back to v. For the left hand side, to integrate a constant, multiply it by whatever variable you are integrating against (in this case, t) and add a constant. ...

Kajsin 4 Received 2003 October 23; accepted 2004 June 9 ABSTRACT We present surface photometry results for a sample of 11 edge-on galaxies observed with the 6 m telescope at the Special Astrophysical Observatory, Russia. ... We find from a comparison of photometric scales that the stellar disks of LSB galaxies are thinner than those of high surface brightness ( HSB) galaxies. ... UGC 11301 .. ...
