An attack helicopter is equipped with a 20- mm cannon that fires 87 g shells in the forward direction with a muzzle speed of 853
uysha [10]

Answer

given,

mass of the shell = 87 g = 0.087 Kg

speed of the muzzle = 853 m/s

mass of the helicopter = 4410 kg

A burst of 176 shell fired in 2.93 s

resulting average force = ?

momentum of the shell = m v

                                       = 0.087 x 853

                                       = 74.21 kgm/s

momentum of 176 shell is = 176 p

                                          = 176 x 74.21

                                          = 13060.96

momentum of helicopter = - 13060.96 kgm/s

amount of speed reduce a = \dfrac{13060.96}{M}

                                          a= \dfrac{13060.96}{4410}

                                          a = 2.96 m/s²

velocity  = \dfrac{2.96}{2.93}

      v = 1.01 m/s

The reason why the position of an electron cannot be measured with absolute precision is:
LenKa [72]
They are too small are never in the same place. Electrons are constantly moving in random motion within the electron cloud, making them impossible to follow.

How do you determine: how many significant figures should you to round to when doing addition and subtraction?
rodikova [14]
The rule is always the same. Your final answer must have the same number of significant figures as the least accurate value in the calculation (one with the least number of significant figures) I hope this makes sense
