A force of 40.0 N accelerates a 5.0-kg block at 6.0m/s^2 along a horizontal surface.

a. how large is the frictional force?
b. what is the coefficient of friction?

Please help me with these questions.
I'm having trouble understanding them.

I have posted this question before, and have seen many different, and varying answers. There seems to be a problem with this question.

LS: Ag - 2, C - 1, O - 3
RS: Ag - 2, C - 1, O - 5
