Question

In a car race, car A takes 2 s less than car B and passes the
finishing point with a velocity v more than the velocity with which
car B passes the point Both the cars start from rest and travel
with constant accelerations of car A = 3 m/s2and car B = 2 m/s2 the
value of v is? ans is 4 9 m/s
