Question

The forces acting on a body(s) are :F1=30n(60 north of west) f2=40 N (30 north of west)

a-represent the forces acting on (s) on a free body diagram

b-Calculate the magnitude of the net force acting on (s) and indicate its direction

Answer 1

Answer

a) net force is

F_n= $(F+F') cos 60°$

= (40+30) $*0.5$

=35N

b) direction in j or y direction.
