Homework Statement


A block of mass 1kg has a coefficient of static friction of .5. If a 7N force is applied to the block what distance can the block travel? Coefficient of kinetic friction is .3


Homework Equations


F=ma


The Attempt at a Solution


I found the static frictional force to be (.5)(9.8)(1)=4.9N so the Fnet of the initial force applied is 2.1N. However I do not know how to find the distance the block traveled from there? Anybody know how to do this?

You know the Coefficient of kinetic friction.Thats what you need here.

I know that I need to use kinetic friction but I don't how to use it with what I am giving. I think I might need to find velocity but how could I find that?
 
(you may redefine the question with "If a 7N force is applied to the block what distance can the block travel?,Until coming to a stop.
I think your question needs to be a bit clear.

Find the kinetic frictional force and using F=ma,find the deceleration of the block when it is initially traveling with a constant force.(you may redefine the question with "If a 7N force is applied to the block what distance can the block travel?,Until coming to a stop.

Note:you may also need the kinematics equations
V=u+at
s=1/2(u+a)t2
s=ut+1/2at
v2=u2+2as

Using V^2=u^2+2as, I know that V will be 0, a will be 2.94 and s is the distance which am trying to find, I just don't know how to find u.
 
Make your question clear.A Force of 7N is applied for how many seconds?If we keep applying it forever,it won't stop moving at all.
