A student investigates the collision of two gliders A and B on a linear air-track. A card is attached to glider B, as shown in Fig. 2.1. light gate connected to data logger air-track card glider A glider B bench Fig. 2.1 Glider B has a mass M. A mass m is added to glider B. Glider A travels at a constant velocity u towards the stationary glider B. The gliders then collide and move together towards the light gate. The card passes through the light gate which is connected to a data logger. The student records the velocity v of the two gliders from the data logger. The student changes the mass m and repeats the experiment. It is suggested that v and m are related by the equation Au = (M + m + A)v where A is the mass of glider A. 1
