Rounded off values might be slightly off from the real answers.
Update: Please refer the attached correction.
Correction: In part (c) (iii), the new velocity must be added to the velocity of attacker vehicle and calculated again.
The correction required in c(111) pls explain, bit confusing why relative velocity comes in.
Sorry pls explain how did you arrive at 2.716.....also why not Tn2?
It's 2 times 716. Made it clear on this solution
Thanks got it.
