Question

Out of the two cars A and B, car Ais moving towards
east with a velocity of 10 m/s whereas B is moving
towards north with a velocity 20 m/s, then velocity of
A w.r.t. B is (nearly)

(1) 30 m/s
(2) 10 m/s
(3) 22 m/s
(4) 42 m/s​

Answer 1

Answer:

distance traveled by A in 1 sec=10m

distance traveled by Bin 1sec=20m

distance between them after 1sec=squre root 400+100

=22.2m

so velocity is22.2m/s
