WebFigure 3.8 The velocity is positive for the first part of the trip, zero when the object is stopped, and negative when the object reverses direction. Significance During the time interval between 0 s and 0.5 s, the object’s position is moving away from the origin and the position-versus-time curve has a positive slope. 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 ...
