- Part B Choose frame S'so that its origin is located at the center of the train. Take the direction of motion of the train (eastward) to be the positive direction of x. Let the instant when the light flashes be t =0 s. What are (2,t) and (z,), the spacetime coordinates of event A and B in S? Note that the time coordinate of an event is the time at which the event actually occurs, not the time at which an observer receives information about it (e.g. when a passenger hears the sound of the bell or the siren). Express space coordinates in meters and time coordinates in microseconds to three significant figures. Enter a value for each coordinate; separate your answers by commas. Do not enter parenthesis.

Part B Choose frame S'so that its origin is located at the center of the train. Take the direction of motion of the train (eastward) to be the positive direction of x'. Let the instant when the light flashes be t = 0 s. What are (z,t) and (za, ta), the spacetime coordinates of event A and B in S? Note that the time coordinate of an event is the time at which the event actually occurs, not the time at which an observer receives information about it (e.g. when a passenger hears the sound of the bell or the siren). Express space coordinates in meters and time coordinates in microseconds to three significant figures. Enter a value for each coordinate; separate your answers by commas.

Lorentz Transformations - 1 Learning Goal: To practice Problem-Solving Strategy 36.1 Relativity. A rocket train car that is 30 m long is traveling from Los Angeles to New York at v = 0.5c when a light at the center of the car flashes. When the light reaches the front of the car, it immediately rings a bell. Light reaching the back of the car immediately sounds a siren. A bicyclist waiting to cross the tracks sees the light in front of her at the instant when it flashes. Are the bell and siren simultaneous events for the bicyclist? If not, what time delay does the bicyclist hear between the events? %3D
