Answer 2

Answer:

Two cars are moving along a straight line AB . Car A starts from rest from point A and moves toward point B The acceleration of car A starts from ( 0 ) m / s and increases at a rate of ( 2 m / s2 / s ) ( means 2A - 21 m / s ) . Car B starts form B and moves toward A. The acceleration of B starts from ( 0 ) m / s and increases by a rate of ( 4m / s / s ) . Both cars are met at a distance of ( 2/3 ) of total AB distance as measured from A. Find : ( a ) the velocity of each car when they met . ( b ) Length of AB in m .
