Question: (a) In Example 6.7 (Section 6.3) it was calculated that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously.

(a) In Example 6.7 (Section 6.3) it was calculated that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously. How large would the coefficient of static friction p-, have to be to keep the glider from springing back to the left?
(b) If the coefficient of static friction between the glider and the track is p-, = 0.60, what is the maximum initial speed V, that the glider can be given and still remain at rest after it stops instantaneously? With the air track turned off, the coefficient of kinetic friction is P-k = 0.47.
