## Explain concpet of friction, Physics

Assignment Help:

A 0.17-kg hockey puck leaves the stick on a slap shot travelling 21 m/s. If no other forces act on the puck, friction eventually will bring it to rest 62 m away.

a. Based on these data, verify the value of μk for this hockey puck on ice.

b. Will the answer change if a puck of dissimilar mass, but same material and shape is used? Describe why or why not.
