The discussion revolves around a physics problem involving a hockey puck sliding on ice, where the effects of friction are examined. The problem presents a scenario with specific parameters such as mass, initial speed, and the coefficient of friction, leading to a question about the work done by friction as the puck comes to a stop.
Participants are actively engaging with the problem, offering hints and prompting each other to consider the definitions of work and energy. There is a focus on understanding the initial energy of the puck and its relation to the work done by friction, but no consensus has been reached on a specific approach or solution.
Participants note that the problem may not require certain calculations, such as the force of friction or the distance over which it acts, which could influence the direction of the discussion.
What have you done so far? Hint: the solution does not require you to find the force of friction or the distance over which it applies.blongmoua said:Homework Statement
A hockey puck with a mass of .25kg is sliding along a slippery frozen lake with an initial speed of 60 m/s. Coefficient of friction between the ice and the puck is .03. Friction eventually causes the puck to slide to a stop. What is the work done by friction.
