What initial distance is Kathy’s book from the floor if the book contains 196 J of potential energy and has a mass of 5 kg? What is its velocity as it hits the floor?

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?

Convection occurs when thermal energy is transferred by the movement of

You can melt ice by applying pressure because the solid/liquid line has a slope.
