What is the magnitude of the normal force on the bag?
Answer in units of N.

41.576 N

Explanation:

Resolving force in the inclined plane in the x and y directions gives us;

F_x = mg sin θ

F_y = mg cos θ

Thus;

F_x = 4.8 × 9.81 × sin 28

F_x = 22.106 N

F_y = 4.8 × 9.81 × cos 28

F_y = 41.576 N

We can use Newton's second law to find the normal force.. Thus;

N - F_y = 0.

Where N is normal force;

N = 41.576 N
