Problem 6-7 Friction coefficient - Part 5 - B

A hockey puck travels \(33\; m\) along an ice rink before coming to rest. Its initial speed was \(11\;m/s\).

(a) What is the magnitude of the acceleration of the puck?
(b) What is the coefficient of kinetic friction between the puck and the ice?

Accumulated Solution

\(v_x{^2} = v_{0x}{^2} + 2a_xx \\ a_x = -1.83\; m/s^2 \; \text{ (answer to (a))}\)

\(F_K = \mu_KF_N \\ F_N = mg\)

Correct.

Use Newton's 2^nd law to calculate \(\mu_K\) before continuing;
