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. It can be shown that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously.

If the coefficient of static friction between the glider and the track is μs = 0.85, what is the maximum initial speed v1 that the glider can be given and still remain at rest after it stops instantaneously?
