<p>In a particle accelerator, a neutron is traveling at a speed of 0.7 c, as measured by you in a laboratory. This neutron decays (becoming a proton), ejecting an electron. If you measure the electron’s speed to be 0.5 c, traveling in the same direction as the neutron, what was the relative speed between the electron and neutron when the neutron decayed? Was the electron ejected forward or backwards relative to the neutron’s motion, as “seen” by the neutron?</p>


According to Earth-based observers, the space time coordinates of a collision between two asteroids are <math display='inline'><mrow><mo stretchy='false'>(</mo><mi mathvariant="normal">x</mi><mo>,</mo><mi mathvariant="normal">t</mi><mo stretchy='false'>)</mo><mo>=</mo><mo stretchy='false'>(</mo><mn>3.0</mn><mo>&#x00D7;</mo><msup><mn>10</mn><mrow><mn>11</mn></mrow></msup><mi mathvariant="normal" class="MathML-Unit">m</mi><mo>,</mo><mo rspace="thickmathspace">&#x2062;</mo><mn>450</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">s</mi><mo stretchy='false'>)</mo></mrow></math>.

<p>In a lab frame, S, an object crosses a distance of 15 m in 10 s. In an initially aligned frame S', moving at 1000 km/s in the x-direction relative to S, how far a distance does the object have to travel, and in what time does it travel the distance?</p>
