Two Trains Leaving a Station
Difficulty: Easy · Topics: Relative Motion, Kinematics
Bekatdan jo‘nagan ikki poyezd
Two trains initially at rest leave a station at the same time. Train A moves in a straight line with acceleration a A = 2 m/s^2 and train B in the opposite direction with a B = 1 m/s^2. What is the speed of B relative to A, 10 seconds after departure?
Dastlab tinch turgan ikki poyezd bir vaqtda bekatdan jo‘naydi. A poyezd to‘g‘ri chiziq bo‘ylab a A = 2 m/s^2 tezlanish bilan, B poyezd esa qarama-qarshi tomonga a B = 1 m/s^2 tezlanish bilan harakatlanadi. Jo‘nagandan 10 soniya o‘tgach, B ning A ga nisbatan tezligi nimaga teng?
