Почему в правой части формулы стоит знак "минус"? Почему не совпадают размерности в левой и правой частях формулы? И из какого опыта нужно вывести эту формулу?
Формально из формулы следует, что Но в этом нет смысла.
Вагон массой m ударяет в пружинный амортизатор жёсткостью с, имея в момент начала удара скорость V0 . Определить максимальную деформацию пружины амортизатора, пренебрегая её массой и полагая её недеформированной перед ударом. вот сама задача
при решении использовали теорему об изменении кинетеческой инергии
Т-Т0=сумма Акинетической энергии вогона от удара Т=0 кинетической энергии вогона при max деформации пружины Т0=mV02/2 сумма Аке = -с/2*λ2, где λ2 max деформации пружины
В мини-форуме консультации, уточняя заданный вопрос, Вы писали Цитата: san2ches
Вагон массой m ударяет в пружинный амортизатор жёсткостью с, имея в момент начала удара скорость V0 . Определить максимальную деформацию пружины амортизатора, пренебрегая её массой и полагая её недеформированной перед ударом.

Т-Т0=сумма Акинетической энергии вогона от удара Т=0 кинетической энергии вогона при max деформации пружины Т0=mV02/2 сумма Аке = -с/2*[$955$]2, где [$955$]2 max деформации пружины
В таком случае, как я понимаю,
Последняя формула даёт ответ на Ваш вопрос.
Вы забыли поставить знак "минус" в левой части уравнения.
С уважением.
