How many forces are acting on the 10 kg box? Select all that apply

• weight (w)

• Normal force (Fn)

• Tension 1 (T1)

• Tension 2 (T2)

This free body diagram represents all the forces acting on a hanging object ( without x and y components)

This free body diagram represents the x and y components of both tensions and weight

A cable with a tension of 850 N at 60° will have a y-component equal to:

• 425 N

• -38.56 N

• 736.12 N

• 45.96 N

The normal force is represented by the symbol

• N

• F_K

• F_N

• µ_K

The total amount of all the forces on an object is called the __________________________.

• balanced force

• unbalanced force

• net force

• normal force

Calculate the net force.

• 60 N right

• 60 N left

• 10 N left

• 10 N right

Calculate the net force

• 50 N up

• 50 N down

• 30 N up

• 30 N down
