more general lorentz transformations 15 pts we normally assume that the origins of two inertial frames coincide at t-t'-0 this way we find lorentz' transformations: suppose instead that when t = t, the origin of s' (which, in s. is moving to the right as usual along the col n mon 1: t, axis with speed u) has abscissa x x (neglect y and z) and the s' clock at the origin of s' reads 0 at this moment. (a) how do the lorentz transformations from s to s' need to be modified? do not rederive you don't need any fancy or long math. try introducing an auxiliary frame of reference that reduces this problem to the usual case (b) what about from s' to s? the same advice as in (a) applies.] c) write these in matrix form

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
