Question

A 1 kg puck sliding on a horizontal shuffleboard court is slowed to rest by 1 point

Answer 1

Answer:

miu = 0.31

Explanation:

The friction force is defined as the product of the normal force by the coefficient of friction.

$f=miu*N$

where:

f = friction force = 3 [N]

miu = friction coefficient

N = normal force [N]

The normal force on a horizontal surface can be calculated by means of the product of mass by gravity.

where:

m = mass = 1 [kg]

g = gravity acceleration = 9.81 [m/s²]

$N=m*g\\N=1*9.81$

$N= 9,81 [N]$

Now replacing in the equation above, we can find the friction coefficient.

$miu=3/9.81\\miu = 0.31$
