Решение. №6 (с. 28)
Решение
Поскольку полный текст вопроса отсутствует, проанализируем каждый из предложенных графиков зависимости скорости от времени и определим, какой тип движения он описывает. Зачастую в таких задачах требуется выбрать график, соответствующий определенному типу движения, например, равноускоренному.
1) 1
График 1 показывает, что скорость тела со временем увеличивается. Зависимость нелинейная, причём наклон графика (который соответствует ускорению) со временем возрастает. Это движение с переменным, увеличивающимся ускорением.
2) 2
На графике 2 скорость сначала возрастает, достигает максимального значения, а затем убывает до нуля. Направление движения не меняется (скорость всегда неотрицательна). Ускорение при этом не является постоянным: сначала оно положительное и уменьшается, затем становится отрицательным.
3) 3
График 3 является прямой линией с отрицательным наклоном. Это означает, что движение происходит с постоянным отрицательным ускорением ($a = \text{const} < 0$), то есть является равноускоренным. Начальная скорость положительна. В некоторый момент времени скорость становится равной нулю, после чего тело начинает двигаться в обратном направлении (скорость становится отрицательной). Такой график описывает, например, движение тела, брошенного вертикально вверх (если ось скоростей направлена вверх).
4) 4
На графике 4 скорость постоянна и отрицательна ($v = \text{const} < 0$). Это означает, что тело движется равномерно и прямолинейно в направлении, противоположном положительному направлению оси. Ускорение тела равно нулю.
Из всех представленных графиков только график 3 описывает равноускоренное движение, которое является одним из фундаментальных видов движения, изучаемых в кинематике. Вероятнее всего, в задаче имелось в виду именно такое движение.
