Assuming both objects are at rest, which side of the string has more tension?

• There is more tension on the side by M1
• There is more tension on the side by M2
• The tension on both sides is the same

To find the normal force

• mg
• sin(θ)mg
• cos(θ)mg
• tan(θ)mg

If both boxes are at rest in the picture, what other force is equal to the tension in the string?

• (M1)(g)sin28⁰

• (M1)(g)cos28⁰

• (M2)(g)sin28⁰

• (M2)(g)cos28⁰

If there is no friction, a = 

• 9.8 m/s/s
• 3.35 m/s/s
• 8.37 m/s/s
• 9.21 m/s/s

Weight can be expressed as...

• mg

• sin(θ)mg

• cos(θ)mg

• tan(θ)mg

If there is no friction, then the acceleration would be equal to

• mg

• sin(θ)mg

• g

• sin(θ)g

If an object is at rest on an inclined plane, which of the following forces is greatest?

• Normal Force
• Friction
• Weight
• Both Normal Force and Weight are equal, so they both are the greatest.

Three forces act on a box in an inclined plane as shown in the diagram below. [Vectors are not drawn to scale.] If the box is at rest, the net force acting on it is equal to

• the weight

• the normal force

• friction

• zero
