Question

A cyclist A is moving due East at 60km/hr whereas a Cyclist B is moving N60°W at 50Km/hr.Find the velocity of A relative to B.

Answer 1

Answer:

Explanation:

then v(man) = 10i

and v(rain) = -vj                          

i and -j are the directions for man and rain

so v(rain w.r.t. man) = -vj-10i

so tan10 = 10/v so v = 10 cot10
