A car travels due east on a level road for `30 km`. It then turns due north at an intersection and travels `40 km` before stopping. Find the resultant displacement of the car.

Text Solution

Verified by Experts

The correct Answer is:
`50 km, 53^(@)` north of east
Displacement
`=sqrt((30)^(2)+(40)^(2))=50 km`
`tan alpha=40/30 rArr alpha=53^(@)N` to E
