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 aA = 3 m s–2 and
aB = 2 m s–2. The value of v is
A 2.45 m s–1
B 4.90 m s–1
C 7.35 m s–1
D 9.80 m s–1
