09. On a two lane road, a car A is traveling with a speed of 36kmph. Two cars B and C approach car A in opposite direction with a speed of 54kmpheach. At a certain instant
when the distance AB equals AC, both BEING 1 km, B decides to overtakes A before C
does. What maximum acceleration for B is required to avoid an accident?​

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
