Draw all the forces acting on the object below and label the forces: 4. A box is moving to the right with a positive acceleration on a horizontal surface with friction.
5. A box is being pulled to the right with an applied force at an angle of 30° above the horizontal at a constant speed.
6. A box is being pulled upward at constant speed.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
