тело свободно падает с высоты 45 м . какой путь проходит тело за последнюю секунду

Ответы

Автор ответа: dnepr1

Путь при падении S = (gt²)/2.
Если принять g = 10 м/с², то путь равен:
- за 1 с = 5 м,
- за 2 с = 20 м,
- за 3 с = 45 м.
То есть за последнюю (третью) секунду тело проходит путь, равный 45 - 20 = 25 м.
