A42.3 kg girl and a 7.93 kg sled are on the surface of a frozen lake, 15.0m apart and linked by a rope, but not moving yet. then the girl pulls on the rope, exerting a 5.76 n force on the sled, pulling it toward her. how far from the girl's original position do they meet?
Answers: 3
with this we can get both accelerations; solving for acceleration 
. Now 
and
. Then knowing that they both travel at the same time and assuming that the distance among the girl and the sled is: 15.0-x, so, 
and
, solving for the time we get:
and 
with this equations we solving for the x that is the distance between the girl and the sled after the apply the force and we get:
. Finally we get:
and replacing the values we have got:
so 
so x=2.37 (meters).

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
