the power of the 2nd car is double times the power of 1st car.. and hence 2nd will make it to the top of mountain first and first car will take double amount of time
These are all the characteristics of what is called the adiabatic process. This process occurs when there is no transfer of heat between the surroundings and the thermodynamic system. This is a key process for thermodynamics and it is of great importance for the first law of thermodynamics.
#Case -1
If Pulling force is less than frictional force the object won't move .
#Case-2
If Pulling force is greater than frictional force then object will be .
In order to calculate friction force you need Limiting friction first .

u s is coefficient of static friction and N is normal reaction
Or
