... The girl is hanging, at rest, from a clothes line. Which side of the line is more likely to break? First, identify forces: Three forces are acting on her – downward weight, tension in left line, and tension in right line. The question is asking, which tension is greater. Because she’s at rest, the n ...

... A 10.0-kg box rests on a horizontal floor. The coefficient of static friction is 0.40 and the coefficient of kinetic friction is 0.30. Determine the maximum static frictional force and the kinetic frictional force. Would the box move if a 10 N force was applied? If so, what would be its acceleratio ...

... The model airplane has a mass of 0.90 kg and moves at a constant speed of 19 m/s on a circle that is parallel to the ground. The path of the airplane and the guideline lie in the same horizontal plane because the weight of the plane is balanced by the lift generated by its wings. Find the tension in ...

Starting from rest, objects A and B are pushed by equal forces (equal magnitudes and same direction) for equal time intervals on a horizontal frictionless surface. At the end of the push, compared to the momentum of object A, the momentum of object B is ...
