Автомобиль , масса которого равна m=2160кг, начинает двигаться с ускорением , которое в течении t секунд остается неизменным и проходит за это время пусь s=500 метров. значение силы（в ньютонах）приложеной а это время к автомобилю , равно f=2ms/t^2 . определите наибольшее время после начала движения автомобиля, за которое он пройдет указанный путь, если известно , что сила f приложенная к автомобилю, не меньше 2400н , ответ дайте в секундах

2mS/t2 ≥ 2400

2mS ≥ 2400∙ t2 

2 ∙ 2160 ∙ 500 ≥ 2400∙ t2 

2160000 ≥ 2400∙ t2 

t2 ≤ 2160000 / 2400

t2 ≤ 900

t ∈ [-30;30] и t ≥ 0
