A particle starts from a point A and travels along the solid curve shown in figure. Find approximately the position B of the particle such that the average velocity between the positions A and B has the same direction as the instantaneous velocity at B.

Answer

C

Explanation

AT position B instasntaneous velocity has direction along `vec(BC)` For average velocity between A and B `V_(av)=displacement/time
=(vec(AB)/t)
` We can see that `vec(AB) is along (BC) i.e. they are in same direction. The point is B (5m, 3,).
