A block weighing 11.05 N rests on a 28 degree incline.

(a) Find the normal force exerted by the plane on the block out of the plane

(b) Find the frictional force exerted by the plane on the block up the slope.
c) Find the magnitude of the total force exerted by the plane on the block

(d)Find the normal force and the frictional force exerted by the block on the plane.

1 answer

(d) is for this
normal force into the plane
and the frictional force down the slope
