Q. In a car race, car $A$ takes $20$ seconds less than car $B$ to finish and passes the finishing point with speed $v$ more than that of car $B$. Assuming that both cars start from rest and travel with a constant acceleration of $50{\text{m/s}}^2$ and $40{\text{m/s}}^2$ respectively, what is the value of $v$ ?
