Если ты имеешь ввиду наклонены под некотрым углом альфа к горизонту? Если ты это имеешь ввиду, тогда нужно строить проекцию скорости на ость горизонтали. Тогда формула для скорости будет иметь вид:

V(->)=VCosA

Равнодействующая будет находиться так же как и обычно, только в формулке вместо V пиши VcosA.


Manvey: Что за ось горизонтали?
Manvey: Можете сделать наглядную иллюстрацию?
MrBagz: другими словами просто земля.
MrBagz: т.е ось Х направленная вправо
