Answer:
v = 0.76 [m/s]
Explanation:
The linear momentum generated by the shot must be calculated. This can be calculated using the following expression.
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
![P=0.004*380\\P=1.52[kg*m/s]](https://tex.z-dn.net/?f=P%3D0.004%2A380%5C%5CP%3D1.52%5Bkg%2Am%2Fs%5D)
Now we can calculate the recoil velocity, because the momentum is equal for the rifle.
![P=m*v\\v = P/m\\v = 1.52/2\\v = 0.76[m/s]](https://tex.z-dn.net/?f=P%3Dm%2Av%5C%5Cv%20%3D%20P%2Fm%5C%5Cv%20%3D%201.52%2F2%5C%5Cv%20%3D%200.76%5Bm%2Fs%5D)
Answer:
One way to increase acceleration is by changing the velocity.
Answer:
<h2>15 Ns</h2>
Explanation:
The impulse of an object can be found by using the formula
impulse = force × time
From the question we have
impulse = 0.5 × 30
We have the final answer as
<h3>15 Ns</h3>

Answer: The Forces Between Protons at Nuclear Distances. Two protons are subject to two forces; the nuclear force and the electrostatic force. When they are very close together the nuclear force is dominant and when they are far apart it is the electrostatic force which is dominant.
