B)5000 joules
C) 5 kilocalories
Answer is C
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 =
a=
a = 2.96 m/s²
velocity = \dfrac{2.96}{2.93}
v = 1.01 m/s
because a chemical change takes time
The answer to the question being asked on what do you called when the movement of the bones around a fixed angle without lateral displacement is ROTATION. Rotation movement allows the bone to move in a single long axis without being displaced.
All the junk in space is because of people on Earth launching things into space.
