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 ?k=0.47. It can be shown that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously. Part A) How large would the...
