Step 2 : Vector components.
Hey! These vectors already line up. On to Step 3 .

Step 3 : Equations.
Remember, weight is equal to mass times the gravitational field, or mg .

Step 4 : Solve.

T = 50  N

The same    box is  now hung    by  two ropes.  One makes   a   45-degree   angle   with    the ceiling;    the other   makes

a   30-degree   angle   with    the ceilign.    What    is  the tension in  each    rope?

Step 1 : Free-body diagram.

Step 2 : Vector components.
