+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.the car is going in the positive x-axis (i) so the flag will move in opposite direction (-ve x-axis(-i))- now just vectorially add the two velocity vectors and divide them by the magnitude to get direction vector
Ig u can just assume the car to be going in any direction +x or -x or by looking at the options u can see none of the option contain 13 as the magnitude of resultant vector in denominator
so it must be going in the -x
isnt the flag supposed to be waving in opposite direction tho
Car moves in +ve/-ve direction, the flag here moves in the opposite direction of car
car should move in +ve x-axis since the vector given has a direction i and not -i
Oh yah +ve only
Use the formula
It's um the value of a + b /√a²+b²
thank u guyss....
i appreciate your help
