1. The Roadrunner has a velocity of 0.9 c [North] and Speedy Gonzales has a velocity of 0.8 c [South]. If they are approaching each other, then determine their relative velocity. 2. Supergirl is flying at 0.9 c [ East] and The Flash has a velocity of 0.99 c [East]. If The Flash is catching up to Supergirl from behind Supergirl then determine their relative velocity. 3. Black Widow is travelling at 0.5 c [East] and Loki has a velocity of 0.4 c [West]. If they are receding from one another, then determine their relative velocity.4. The Enterprise is travelling at 0.999 c [East] and the Star Destroyer has a velocity of 0.99 c [ East]. If they are receding from one another then determine their relative velocity. 5. If the Tardis space-time-ship has a velocity of 0.5 c [E] and The Heart of Gold starship also travelling [E] has a relative velocity of 0.1 c [receding] then determine the velocity of the Heart of Gold starship. 6. If the Prometheus space exploration vessel has a velocity of 0.99 c [E] and the starship Daedalus has a relative velocity of 0.999 c [approaching head-on from the E] then determine the velocity of the starship Daedalus.1. Protons normally have a rest mass of 1.6TK10'\" kg. In the Large Hadron Accelerator at CERN in Europe protons were accelerated to 99.9993'9'3 of the speed of light in 2014. Determine the relativistic momentum and kinetic energy of one of these protons. 2. If the Flash masses 100 kg at rest and then runs across the Atlantic Ocean at 99% the speed of light then determine his relativistic kinetic energy and relativistic momentum. Compare them to classical mechanics kinetic energy and momentum. What is the percentage error if we naively use classical mechanics? "*3. If Storm normally masses 60 kg at rest and she somehow manages to reach a relativistic momentum of 4.5 trillion N s then determine her relativistic velocity. 4. Marvin the Martian's UFO has a rest mass of 100 tonnes. He accidently calculates his kinetic energy to be 4.5XID\" J using classical mechanics. Determine his more truthful and correct relativistic kinetic energy. ? \"*5. How fast does an object (anything, maybe a widget] have to be moving to have a percentage error of 49% between classical momentum and relativistic momentum?I it \"*6. An electron has a rest mass of 9.1 leD'\" kg and protons normally have a rest mass of 1.67X10'\" kg. A proton is moving East at 100 nits and an electron is moving West at 0.999 c. They collide inelastically forming a Hydrogen atom. Determine the resultant velocity of the Hydrogen atom, and be sure to use the electron's relativistic momentum
