Answer 2

Answer:

128.60

Step-by-step explanation:

The initial speed of the car is 100 km/hr

Convert it to m/s: 100×5/18=27.77m/s

The final speed of the car is 0

Acceleration of the car is -3m/s^2

According to equation: v^2-u^2=2as

0^2-(27.77)^2=2×(-3)×s

-771.60=-6s

s=-771.60/-6

s=128.60m
