Positions of two vehicles A and B with reference to origin O and their velocities are as shown.

Options

  1. Athey will collide
  2. Bdistance of closest approach is 100 m .
  3. Ctheir relative velocity is 40 3 ~m / s
  4. Dtheir relative velocity is 20 3 ~m / s

Correct answer

C. their relative velocity is 40 3 ~m / s

Step-by-step solution

t= ( 200 3 )+ ( 100 3 ) (40 / 3 ) =7.5 ~s
