# 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 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

Since,

For second event in the S' frame

Since,
