JEE Main 30 July 2022, Shift 2, Physics Q2

Question 2 of 90 in this shift, Physics question 2 of 30, Section A.

Two trucks A and B are approaching each other on a straight path with the velocities of 16 m/s and 20 m/s respectively. When 200 m apart their drivers see each other and applies the breaks simultaneously. If the truck A decelerates with 2 m/s2^2 and truck B decelerates with 4 m/s2^2 , what is the distance between them when they finally stop?
  1. (1)14 m
  2. (2)114 m
  3. (3)86 mOfficial answer
  4. (4)64 m
