What the sim shows
The pull on the trolley is the weight of the hanging masses: each 20 g mass weighs 0.2 N. The mass being accelerated is everything that moves, trolley, bars and all five slotted masses, wherever they sit. So moving masses from the trolley to the hanger changes the force but not the mass. With 3 masses pulling, F = 0.6 N on m = 1.0 kg: a = F ÷ m = 0.6 m/s². The gate times the 5 cm card; speed = card ÷ time, and a = v² ÷ 2s. Doubling F doubles a; doubling m halves a: F = m a. The runway is tilted just enough to cancel friction (too little to see). Taking g = 10 N/kg.
