Slow Motion Crash

Slow Motion Crash are an American indie rock band. Formed by former members of Creve Coeur in 2006, the band released their debut album in May 2007. Band members include Brian Fisher (vocals/guitar), Ryan Holmes (guitar/vocals), Melissa Giorgio (bass), Alec Irvin (drums) and Joshua Broughton (keys).

Science in Motion

Solanco High School did not take advantage of a state program called Science in Motion which brings college professors and sophisticated science equipment to the school to raise science awareness and to provide inquiry-based experiences for the students. The Science in Motion program was funded by a state appropriation and cost the school nothing to participate. Elizabethtown College offers the program in Lancaster County.

Motion pictures

The film Where the Buffalo Roam (1980) loosely depicts Acosta's life and his relationship with Hunter S. Thompson. Its name is derived from Thompson's article about Acosta, "The Banshee Screams for Buffalo Meat," in reference Acosta's book Autobiography of a Brown Buffalo. Actor Peter Boyle portrayed Acosta, whose character is named "Carl Lazlo, Esquire" and Bill Murray portrayed Thompson. Fear and Loathing in Las Vegas (1998) is a film adaptation of Thompson's novel of the same name, a fictionalized account of Thompson and Acosta's trip to Las Vegas in 1971. Benicio del Toro portrays Acosta, referred to in the film and novel as "Dr. Gonzo," while Johnny Depp portrayed Thompson (under the alias of Raoul Duke). The Rise and Fall of the Brown Buffalo (2017) is a documentary of the life and career of Acosta with dramatic reenactments. The documentary was directed by Phillip Rodriguez and produced by Benicio del Toro, who portrayed Acosta in Fear and Loathing in Las Vegas.

Equations of motion

PositionIn a hyperbolic trajectory the true anomaly displaystyle theta is linked to the distance between the orbiting bodies ( r displaystyle r, ) by the orbit equation: r = 1 e cos displaystyle r=frac ell 1ecdot cos theta The relation between the true anomaly and the eccentric anomaly E (alternatively the hyperbolic anomaly H) is: cosh E = cos e 1 e cos displaystyle cosh E=cos theta e over 1ecdot cos theta or tan 2 = e 1 e 1 tanh E 2 displaystyle tan frac theta 2=sqrt frac e1e-1cdot tanh frac E2 or tanh E 2 = e 1 e 1 tan 2 displaystyle tanh frac E2=sqrt frac e-1e1cdot tan frac theta 2 The eccentric anomaly E is related to the mean anomaly M by Kepler's equation: M = e sinh E E displaystyle M=esinh E-E The mean anomaly is proportional to time M = a 3 . ( t ) , displaystyle M=sqrt frac mu -a^3.(t-tau ), where is a gravitational parameter and a is the semi-major axis of the orbit.Flight path angleThe flight path angle () is the angle between the direction of velocity and the perpendicular to the radial direction, so it is zero at periapsis and tends to 90 degrees at infinity. tan ( ) = e sin 1 e cos displaystyle tan(phi )=frac ecdot sin theta 1ecdot cos theta VelocityUnder standard assumptions the orbital speed ( v displaystyle v, ) of a body traveling along a hyperbolic trajectory can be computed from the vis-viva equation as: v = ( 2 r 1 a ) displaystyle v=sqrt mu left(2 over r-1 over a

ight) where: displaystyle mu , is standard gravitational parameter, r displaystyle r, is radial distance of orbiting body from central body, a displaystyle a,! is the (negative) semi-major axis.Under standard assumptions, at any position in the orbit the following relation holds for orbital velocity ( v displaystyle v, ), local escape velocity ( v e s c displaystyle v_esc, ) and hyperbolic excess velocity ( v displaystyle v_infty ,! ): v 2 = v e s c 2 v 2 displaystyle v^2=v_esc^2v_infty ^2 Note that this means that a relatively small extra delta-v above that needed to accelerate to the escape speed results in a relatively large speed at infinity. For example, at a place where escape speed is 11.2 km/s, the addition of 0.4 km/s yields a hyperbolic excess speed of 3.02 km/s. 11.6 2 11.2 2 = 3.02 displaystyle sqrt 11.6^2-11.2^2=3.02 This is an example of the Oberth effect. The converse is also true - a body does not need to be slowed by much compared to its hyperbolic excess speed (e.g. by atmospheric drag near periapsis) for velocity to fall below escape velocity and so for the body to be captured.
