A 2.00-kg block situated on a rough incline is connected to a spring of negligible mass having a spring constant of 100 N/m. The block is released from rest when the spring is unstretched, and the pulley is frictionless. The block moves 20.0 cm down the incline before coming to rest.

Find the coefficient of kinetic friction between block and incline.

2. Relevant equations

PE = KE

F= ma

Ff = [tex]\mu[/tex]F_{n}

[tex]\mu[/tex] = Ff/F_{n}

PE = KE

3. The attempt at a solution

Ff = mgsin[tex]\theta[/tex]

Fn = mgcos[tex]\theta[/tex]

[tex]\mu[/tex] = (mgsin[tex]\theta[/tex])/mgcos[tex]\theta[/tex]

stuck!

mgh = 1/2mv^{2}
