The question as text

A student investigates the collision of two gliders A and B on a linear air-track, as shown in Fig. 2.1. light gate connected to timer bench card L glider A glider B Fig. 2.1 The light gate is connected to a timer. A card of length L is attached to glider B. The mass of glider B and the card is m. Glider B is initially at rest. The student releases glider A so that it travels at a constant velocity u towards the stationary glider B. The gliders collide and then separate. The card on glider B passes through the light gate. The student records the time t for the card to pass through the light gate from the timer. The student changes the mass of glider B and repeats the experiment. It is suggested that the velocity v of glider B as it passes through the light gate and m are related by the equation v = 2uA m + A where A is the mass of glider A. 1
