## Homework Statement

4) In the above figure, the horizontal axis is x measures in meters, the vertical axis is t measured in meters (SR units!)

a) For the pairs of events AB, AC, CB, determine the metric distance between them.

b) For each pair answer whether the first member of the pair could have caused the second member.

See attachment for graph.

## Homework Equations

**3. The Attempt at a Solution [/b**

As the axes are in meters the problem was instantly confusing.

For part a) we assumed spatial distance, so we subtracted distances on the x-axis and found our solution that way.

part b) was easier, we just drew in the causality lines and determined the solution that way.
