In the free body diagram. what is the net force? A) 40 N, right

B) 10 N, right

C) 80 N

D) 32 N, right

None of the suggested solutions.

Explanation:

horizontally, net force is

60cos30 - 20 = 31.96... 32 N right

which might be their desired answer.

There is also a vertical net force component.

vertically, net force is 40 + 60sin30 - 40 = 30 N up

total net force is

√(32² + 30²) = 43.834... 44 N

θ = arctan(30/32) = 43° above horizontal right.
