An air-track glider of mass 0.0 N/m. Initially the spring is unstreched and the glider is moving at 1.

An air-track glider of mass 0.100 kg is attached to the end of a horizontal air track by a spring with force constant 20.0 N/m. Initially the spring is unstreched and the glider is moving at 1.50 m/s to the right. With the air track turned off, the coefficient of kinetic friction is  μk=0.47. How large would the coefficient of static friction μ
