Question

A car starting from a point travels towards east with a velocity of 36 kmph. Another car starting from the same point travels towards north with a velocity of 24 kmph. The relative velocity of one with respect to another is

Answer 1

Answer:

relative velocity =36i-24j  

modulus of relative velocity= $\sqrt{144(9+4)\\}$

=$\sqrt[12]{13}$  ​      kmph

(because the relative velocities will be 24 and 36 in perpendicular directions)
