Question

Two cars A and B are moving along on a straight line .Car A is moving at speed 80km/hr whole car B is moving at a speed 50km/hr in the same direction. Find the magnitude An d direction of 1)th e relative velocity of car A with respect to B 2)th e relative velocity of car B with respect to car A​

Answer 1

Answer:

This is related to relative motion,

Let the two cars moving in the same direction be A and B and the third car be C.

Let the velocity of C be 'u'.

So the velocity of C with respect to B would be. u+30(as they are moving in opposite directions).

Do the speed u+30 would be given by:

=(604)5=u+30

⇒5×460=u+30⇒75=u+30

 

Hence u=45kmph
