A curling stone of mass $19.00 \mathrm{~kg}$ is released with an initial speed $v_{0}=2.788 \mathrm{~m} / \mathrm{s}$ and slides on level ice. The coefficient of kinetic friction between the curling stone and the ice is $0.01097 .$ How far does the curling stone travel before it stops?

Key Concepts

Work-Energy Principle

The work-energy principle states that the work done by all forces acting on an object is equal to the change in its kinetic energy. When friction does work on a moving object, it removes kinetic energy, slowing the object down. This principle offers an alternative method to kinematics for determining stopping distance by equating the work done (force times distance) to the loss of kinetic energy.

Kinematics Equations

Kinematics equations describe the motion of an object under constant acceleration. In the context of a body slowing down due to friction, these equations allow one to link initial velocity, acceleration (or deceleration), and stopping distance. A common equation used is v² = v?² + 2ax, where v is the final velocity, v? is the initial velocity, a is the acceleration, and x is the displacement.

Newton's Second Law

Newton's Second Law states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). This principle is used to relate the frictional force acting on a moving object to its resulting deceleration. By applying this law, one can determine the acceleration (or deceleration) by dividing the frictional force by the mass of the object.

Kinetic Friction

Kinetic friction is the force that opposes the motion of sliding objects. It is characterized by the coefficient of kinetic friction multiplied by the normal force. In situations involving a sliding object on a surface, kinetic friction provides the decelerating force, and knowing its magnitude is crucial to predicting how the object’s speed changes over time and distance traveled until coming to a stop.
