Question

The velocity of a 4.0-n hockey puck,sliding across a level ice surface,decreases at the rate of 0.61m/s2 . The coefficient of kinetic friction between the puck and ice is:

Answer 1

Answer:

Coefficient of the friction on the ice surface is given as

$\mu = 0.062$

Explanation:

As we know that the deceleration of the hockey puck is given as

$a = -0.61 m/s^2$

now we know that force of friction on the hockey puck is given as

$F_f = \mu mg$

now the deceleration due to friction on it given as

$a = \mu g$

now we have

$\mu g = 0.61$

so we have

$\mu = \frac{0.61}{9.81}$

$\mu = 0.062$
