During a hockey game, a 160 g puck is given an initial speed of 10 m/s. It slides 50 m on the horizontal ice before it stops due to friction. What is the coefficient of kinetic friction between the puck and the ice?
Homework Answers
using work energy theorem
workdone by friction = change in kE
u mg d = 0.5 m v^2
u * 9.8* 50 = 0.5* 10^2
u = 0.102
========
comment in case any doubt, will reply for sure.. goodluck

A hockey puck struck by a hockey stick is given an initial speed vi in the positive x direction. The coefficient of kinetic friction between the ice and the puck is μk. (a) Obtain an expression for the acceleration of the puck as it slides across the ice. (Use the following as necessary: μk and g.) ax = (b) Use the result of part (a) to obtain an expression for the distance d the puck slides. The answer should...

A hockey puck sliding across ice has an initial speed of 11 m/s but after 40.0 m has slowed down to 10.5 m/s. (10 pnts) (a) What is the coefficient of kinetic friction between the ice and puck? (b) What would be the coefficient of kinetic friction between the same ice and puck if you glued another identical puck on top of the first one? I'm not sure that I have all of the equations to solve this, so I'm...
