Answer:
<h3>The coefficient of kinetic friction between the puck and the ice isExplanation:
Given :
Initial speed
Displacement m
From the kinematics equation,
Where final velocity, in our example it is zero (
),
acceleration.
From the formula of friction,
Minus sign represent friction is oppose the motion
Where ( normal reaction force )
( ∵
)
So coefficient of friction,
Therefore, the coefficient of kinetic friction between the puck and the ice is 0.12 .
