Question

A hockey puck is given an initial speed of
19 m/s on a frozen pond. The puck remains
on the ice and slides 113 m before coming to
rest.
The acceleration of gravity is 9.8 m/s
2
.
What is the coefficient of friction between
the puck and the ice?

Answer 1

(1/2) M Vo^2 = mu*M*g*X
= (work done to stop)
M cancels out
mu = Vo^2/(2*g*X) = 0.163
is the kinetic friction coefficient
