A car travels at a speed of 60km/hr due north and other at 60km/hr due east. Are the velocities equal? If no, which one is greater? If you find any of the question irrelevant, explain

Dear Nikhil

As velocitiy is a vector quantity. vector quantities have both magnitude and direction. Here magnitude is same but direction is different. we can write V1 = 60j and V2 = 60i. hence velocities are not equal. we can just compare the magnitude and magnitude wise they are equal.

All the best

borth particle are having diff velocities...

 if we take north direction along +ve y axis and east direction along +xaxis then

    velocity of first car is +60j km/hr and velocity of second car is +60i

 thus velocity is diff in direction but same in magnitude ....

Velocity is a vector quantity i.e., it possesess both magnitude and direction and follows the triangular law of vector addition. The given two velocities are not equal since they have the same magnitude i.e., 60km/hr but not the same direction. The second question "which one is greater" would be considered irrelevant since only vectors of same direction can be compared.

No. The velocities are not equal because velocity is a vector quantity and here in the question both the velocities are in different direction as v1=60j^ and v2=60i^.....Also none of them is greater as both have same magnitude
