Question

Какаой путь прошёл поезд при торможении, сбавив скорость с 15 м/с до 5 м/с, если его ускорение было 2 м/с в квадрате.

Answer 1

S=(V₀²-V²)/2a=(225-25)/4=50 м

Answer 2

Calculating the Distance Traveled by the Train During Deceleration

To calculate the distance traveled by the train during deceleration, we can use the following kinematic equation:

v_f^2 = v_i^2 + 2 * a * d

Where: - v_f = final velocity (5 m/s) - v_i = initial velocity (15 m/s) - a = acceleration (-2 m/s^2,
