A car travelling at 60 km/h overtakes another car travelling at 42 km/h. Assuming each car to be 5.0 m long, find the time taken during the overtake and the total road distance used for the overtake.

Text Solution

Verified by Experts

`V_1=60` km/hr=16.6 m/s
`V_2`= 42 km/h=11.6m/s
Before crossing`
`Relative velocity between te cars `=(16.6-11.6)=5 m/s`
`By first car =`5+5=10 m
Time t=S/v=10/5 sec
=2 sec to cross the 2nd car`.` He also covered distasnce which is own length equal its 5m`.
`:.` Total road distance used for the overtake =33.2+5=38 m.
