A 740-kg two-stage rocket is traveling at a speed of 6.40×10^3 m/s away from Earth when a predesigned explosion separates the rocket into two sections of equal mass that then move with a speed of 2.30×10^3 m/s relative to each other along the original line of motion.

Part A: What is the speed of each section (relative to Earth) after the explosion?

Part B: What are the direction of each section (relative to Earth) after the explosion?

a) both away from Earth

b) both towards the Earth

c) one away from Earth and the other towards the Earth

Part C: How much energy was supplied by the explosion? [Hint: What is the change in kinetic energy as a result of the explosion?]

Sam is on a spaceship that travels from Earth to Proxima Centauri at 70% the speed of light, or 0.7c, relative to Earth. Erma is an observer on Earth. From Sam's perspective, 1.35 x 108 seconds passed between when the Earth was near him and when Proxima Centauri is near him First we consider velocity and time: How fast in m/s is Sam moving as measured in the rest frame of the rocket? How fast in m/s is Erma moving...
