a) ...the magnitude of P is 8.0 N. (Hint -- is the block moving?)

b) ...the magnitude of P is 10 N. (Hint -- is the block moving?)

c) ...the magnitude of P is 12 N. (Hint -- is the block moving?)

Fn=-mg

Ff=μFn

I have been stumped with this problem for a long time now. I understand the force being applied is both horizontally and vertically and that I have to decompose each component but I have no clue on how to do it. I tried finding the normal force by multiplying the weight 2.5 kg by 9.8 m/s2 and then using the kinetic mu to find the force of friction but this was wrong. Please help! I am really stumped.
