Rocket a has a positive velocity vt
WebIn each scenario below, use the RHR to determine the direction of force: a) A positive charge's velocity v is directed up in a magnetic field B directed to the left, like this v /\ < B [Select] b) A positive charge's velocity v is directed down in a magnetic field B directed out of the page, like this v \/ o B [Select] Transcribed Image Text ... WebAnswer: Let’s pick one rocket (call it rocket 1) and consider how fast the other rocket (rocket 2) looks in this frame. In the Earth frame, rocket 1 has velocity c=2 and rocket 2 has velocity ¡c=2. Applying the velocity addition law gives v0 2 = v2 ¡v1 1¡v1v2=c2 = (¡c=2)¡(c=2) 1¡(c=2)(¡c=2)=c2 = ¡ 4 5 c; i.e., rocket 2 looks like it ...
