Relative Motion
Two trains approach each other at 40 km/h and 60 km/h. Relative speed is:
Select the correct option:
Solution
100 km/h
When two objects move towards each other (opposite directions), their relative speed is the sum of their individual speeds. Relative speed vrel=v1+v2=40+60=100 km/h. This means to an observer in either train, the other train appears to be approaching at 100 km/h.
