Variable-mass system the momentum of the system varies for Therefore, by Newton's second law Noting that u - v is the velocity of d"m" relative to "m", symbolized as v, this final equation can be arranged as In a system where mass is being ejected or ablated from a main body, the derivation is slightly different. At time "t", let a mass "m" travel at a velocity v, meaning the initial momentum of the system is Since the main body will be losing mass, d"m" will be negative, meaning that at a time "t" + d"t" the momentum of the system becomes
The Velocity of Gary The Velocity of Gary The Velocity of Gary, also known as The Velocity of Gary* *(Not His Real Name), is a 1999 American dramatic comedy film directed by Dan Ireland and written by James Still, based on his homonymous play. It stars Thomas Jane in the title role, along with Salma Hayek and Vincent D'Onofrio. Gary (not his real name, which is never revealed) is a hustler walking through the streets of New York City, looking for business.
