A car is moving de North accelerated in ...

A car is moving de North accelerated in the same direction, while a train is moving parallel to it also due North with a uniform speed of 100 km/hr. At the time when the speed of the car is 80 km/hr, an observer in the finds the car speeding

A

due South at 20 km per hour, accelerated due North

B

due North at 20 km per hour, accelerated due South

C

due South at 180 km per hour, accelerated due North

D

due North at 180 km per hour, accelerated due South

Text Solution

Verified by Experts

The correct Answer is:
A
`therefore` Relative velocity=(100-80)-20 km/h due south It is accelerated due north
