A bus appears to move northwards at a speed of ` 20sqrt3 " km h"^(-1)` To a man diving his car eastwards with speed ` 20 " km h "^(-1)`. Find the velocity of the bus w.r.t ground.

Text Solution

Verified by Experts

The correct Answer is:
40 km/`h^(-1) 30^(@)` east of north .
`barv_("bus")=barv_("car")+barv_("bus w.r.t car")`
