Abox slides across a frozen pond toward the left shore as two children standing on opposite shores pull on the box with ropes. the child on the left shore pulls with a force of 3.0 n, and the child on the right shore pulls with a force of 2.0 n. at a certain instant, the speed of the box is 3.0 m> s.
(a) at that instant, what is the power resulting from each force?
(b) what is the power resulting from both forces?
(c) do your answers to parts a and b change as the box slides? ⦁⦁

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
