Answer 1

Answer:

the scientific study of the structure of substances and what happens to them in differethe scientific study of the structure of substances and what happens to them in different conditions or when mixed with each otherInitial speed of the car is u.

Final speed of the car v=0

Let the retardation of the  car be a.

Using  v2−u2=2aS

Or  0−u2=2aS

⟹ S∝u2   (for same a)

Given :  S=40m    u′=2u

∴ SS′=u2(u′)2=22

Or  40S′=4

⟹  S′=160m
