Answer:
[tex]V =2m/s[/tex]
Explanation:
Given:
Represent
- Susan's velocity with [tex]V_s[/tex]
- Michael's velocity with [tex]V_m[/tex]
[tex]V_m = 7m/s[/tex] eastwards
[tex]V_s = 5m/s[/tex] westwards
Required
Determine how fast is [tex]V_s[/tex] relative to [tex]V_m[/tex]
From the question, one train moves eastwards while the other moves westwards.
This means that travel in opposite travel and the relative speed (V) is calculated as:
[tex]V = V_m - V_s[/tex]
Substitute values for [tex]V_s[/tex] and [tex]V_m[/tex]
[tex]V =7m/s - 5m/s[/tex]
[tex]V =2m/s[/tex]
Hence, the Susan's train is moving 2m/s in relative to Michael's train
