Short Answer

At , a firecracker explodes at in reference frame S. Four seconds later, a second firecracker explodes at . Reference frame S′ moves in the x-direction at a speed of . What are the positions and times of these two events in frame S′?

Position of the events are

Times of the events are

See the step by step solution

Step by Step Solution

Step 1: Given information

We have given,

First firecracker positon =

Second firecracker positon =

Velocity of frame =

We have to find the positon and time of the events in the S' frame.

Step 2: Simplify

Using Galilean transformation,

where x' is coordinate in S' frame.

For first event in the S' frame


For second event in the S' frame
