Під дією сили 150 Н тіло рухається прямолінійно. Якою є маса тіла, якщо рівняння руху має вигляд х=75+30t+0,5t2

Ответы

Автор ответа: igormtkd

Запишемо рівняння:

x = x₀ + V₀·t + a·t² / 2

х = 75 + 30·t + 0,5·t²

x = 75 + 30·t + 1·t² / 2

Знайдемо прискорення:

a = 1 м/с²

Залишилося знайти масу тіла:

m = F / a = 150 / 1 = 150 кг

Відповідь: m = 150 кг

igormtkd: Я старался! И я кстати не списивал, потому что мы сейчас как раз проходим ету тему и я все понял!
