Задача №27.29
Условие
Вожатый трамвая, выключая постепенно реостат, увеличивает мощность вагонного двигателя так, что сила тяги возрастает от нуля пропорционально времени, увеличиваясь на 1200 Н в течение каждой секунды. Найти зависимость пройденного пути от времени движения вагона при следующих данных: масса вагона 10000 кг, сопротивление трения постоянно и составляет 0,02 веса вагона, а начальная скорость равна нулю.Решение
