Using that picture above and this data... A block of mass M slides down a plane at an angle of 37o to the horizontal. The coefficient of kinetic friction = 0.20. The horizontal lines in the picture represent magnitude of forces, in units of the force of gravity on the block. The arrows show directions for forces. DATA: sin(37o)=0.60 cos(37o)=0.80, tan(37o)=0.75. I need to find

A)The 2-letter combination for the total force on the block.

B)The direction of the force on the ramp due to the sliding block. If it is along one of the arrows, select that arrow. If not, select the two adjacent arrows between which that force is directed.

I have no clue what to do or what equation to use...
