but if net Fx = - f(k) the puck shouldn't be moving or at least moving with constant accelleration? isn't this saying that ma= -f(k)? if the opposing forces are the same, how can the object be moving? any force of ma will be canceled out by -f(k) I am so lost...

Can anyone tell me why net Force of x-component = -f(k) in a moving puck? I don't get how the net Force of x-component be just the kinetic friction force. What about the force that the puck is using to be actually moving? shouldn't that force be included in the net Force of x-component...
