A clever engineer designs a "sprong" that obeys the force law F₂ = -q(x - x)³, where x is the equilibrium position of the end of the sprong and q is the sprong constant. For simplicity, we'll let xe =0 m. Then F₂ =-qx³
Energy can be transferred between objects and it can change forms. a. Give an example of a situation where energy is transferred from one object to another. Make sure to describe which object started off with the energy and where the energy went. b. Give an example of a situation where energy changes from one type to another. Make sure to describe the original form of the energy, and what object causes the change in the type of the energy.

spherical R a vertical axis on frictionless bearings (see the figure above). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen a distance d after being released from rest? Use energy considerations. NOTE: Eoncono au ome of and

The force of friction acts upon a rightward-moving car to bring it to a stop. A waiter uses an applied force to balance the weight of a tray of plates as he carries the tray across the room. The force of air resistance acts upon a vertically-falling skydiver. The force of friction acts upon a baseball player as he slides into third base. An applied force is used by a freshman to lift a World Civilization book to the top shelf of his locker. A bucket of water is tied to a string and tension supplies the centripetal force to keep it moving in a circle at constant speed. An applied force acting at 30-degrees to the horizontal is used to displace an object to the…
