Concept explainers

A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine par…

Kinetic Energy and Work-Energy Theorem

In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the d…

Textbook Question

Chapter 8, Problem 50P

A 60 kg skier leaves the end of a ski-jump ramp with a velocity of 24 m/s directed 25° above the horizontal. Suppose that as a result of air drag the skier returns to the ground with a speed of 22 m/s, landing 14 m vertically below the end of the ramp. From the launch to the return to the ground, by how much is the mechanical energy of the skier–Earth system reduced because of air drag?

20. Two small conducting spheres are placed on top of insulating pads. The 3.7 × 10-10 C sphere is fixed whie the 3.0 × 107 C sphere, initially at rest, is free to move. The mass of each sphere is 0.09 kg. If the spheres are initially 0.10 m apart, how fast will the sphere be moving when they are 1.5 m apart?
