A hockey puck is sliding across a frozen pond with an initial speed of 9.5 m/s. It comes to rest after sliding a distance of 37.4 m. What is the coefficient of kinetic friction between the puck and the ice

Explanation:

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 .

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
