A 0.17 kg hockey puck leaves the stick on a slap shot traveling 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, determine the value of μ for this hockey puck on ice.
b) Will the answer change if a puck of different mass, but same material and shape is used? Explain why or how not.

Best ResponseYou've already chosen the best response.1as always, draw your free body diagram. then set the forces in the the x and y directions equal to 0. then solve for the normal force which would be in the y direction then using that and that friction is\[f_k=\mu N\] solve for the coefficient of friction in the force equation in the x direction. you have inititial velocity, mass of the puck, and final velocity. this is all you need for this problem.
