sun of the forces in X and sum of the forces in Y

OpenStudy (anonymous):

Fx=30-40 cos 30=30-40*0.866=30-34.63=-4.64 F=4.64 east

OpenStudy (anonymous):

Fy =40*sin(30)= 20 N north

OpenStudy (anonymous):

so the components of the net force on the cart are 4.64 N east and 20 N north?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

you could combine these forces as one
