A 12.4kg mass is being pushed, from rest, along a level surface. The coefficient of kinetic friction between the mass and the surface is 0.35. The mass is being pushed with a force of 74N [North]. The force is being exerted for 6.4 s. ?
What is the total distance that the mass will travel, before it comes to a rest?

Explanation:
First thing I need is to figure out the Force of Friction:
For that we need the force normal which is equivalent to the Force of weight in this case:
So then the Net force is:
Using the net force I can determine the net acceleration:
Using that:
Since
