Question

For this week's physics lab, the experimental setup consists of two gliders on a horizontal frictionless air track. Each glider supports a strong magnet centered on top of it, and the magnets are oriented so they attract each other. The mass of glider 1 and its magnet is 0.090 kg, and the mass of glider 2 and its magnet is0.198 kg. You and your lab partners are instructed to take the origin to be at the left end of the track and to center glider 1 at x1 = 0.108 m and glider 2 at x2 = 1.760 m. Glider 1 is 9.2 cm long, and glider 2 is 18.2 cm long, and each glider has its center of mass at its geometric center. When the two gliders are released from rest, they will move toward each other and stick. (a) Predict the position of the center of each glider when they first touch. (Enter your answers from smallest to largest.) (b) Predict the velocity that the two gliders will continue to move with after they stick.

Explanation / Answer

apply conservation of center of mass, and conservation of momentum. The gliders will come to rest, and will have the same center of mass at every point along the way
