A light train made up of two cars is traveling at 90 km/h when the brakes are applied to both cars. Know that car A has a mass of 31 Mg and car B has a mass of 20 Mg, and the braking force is 41 kN on each car. Determine:
(a) the distance traveledby the train before it comes to a stop
(b) the coupling force between the cars as the is slowing down.
Answers: 3
, b) 
The real force has the opposite direction. 
![d = \frac{(51000\,kg)\cdot [(90\,\frac{km}{h} )\cdot (\frac{1000\,m}{1\,km} )\cdot (\frac{1\,h}{3600\,s} )]^{2}}{2\cdot (82000\,N)}](/tpl/images/0539/0183/90ede.png)
![a = -\frac{[(90\,\frac{km}{h} )\cdot (\frac{1000\,m}{1\,km} )\cdot (\frac{1\,h}{3600\,s})]^{2}}{2\cdot (194.360\,m)}](/tpl/images/0539/0183/d0ebd.png)
