A car is moving towards east with a speed of `25 km h^-1`. To the driver of the car, a bus appears to move towards north with a speed of `25 sqrt(3) km h^-1`. What is the actual velocity of the bus ?

A

25 km / hr

B

50 km /hr

C

5 km / hr

D

`5sqrt(3)` km/hr

Text Solution

Verified by Experts

The correct Answer is:
b

`V_(m)25 km hr^(-1)`
`v_(tm)=25sqrt(3) km hr^(-1)`
`v_(t)=sqrt(v_(tm)^(2))+v_(m)^(2))=50 km hr^(-1)`
