teja56: how
Payal1999: In the first part of journey, we will get acceleration = -125/18 by using 3rd equation of motion.
Payal1999: Then in 2nd part of journey acceleration remains same. Again use 3rd equation of motion, u will get the stopping distance 80 m

Answer is 40m

Because since retardation is the same and the speed of car is doubled so distance will be doubled.
