Question
During a hockey game, a 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 pick and the ice. A) 0.12 B) 0.10 C) 0.11 D) 0.090 During a hockey game, a puck is given an initial speed of 10 m/s.

A) 0.12 B) 0.10 C) 0.11 D) 0.090 A) 0.12 B) 0.10 C) 0.11 D) 0.090Explanation / Answer
v2-u2=2as
0-(10)2=2*a*50
a=1m/s2
F=uN (N=mg)
ma = umg
u=a/g= .10
