Final answer:
To understand the fundamentals of rifle marksmanship, it is important to grasp the principles of recoil and the forces involved in firing a bullet. This includes understanding the conservation of momentum and using equations to calculate the recoil velocity of the plunger and the average force exerted on it by the gun. Additionally, comparing the force exerted on the gun when the bullet is accelerated to its velocity in a given time can provide further insight.
Step-by-step explanation:
A fundamental of rifle marksmanship is understanding the principles of recoil and the forces involved in firing a bullet. One important concept is the conservation of momentum, which states that the total momentum before firing a bullet must be equal to the total momentum after firing the bullet. This means that the recoil velocity of the plunger can be calculated by using the equation:
m1v1 + m2v2 = (m1 + m2)V
where m1 and v1 are the mass and velocity of the bullet, m2 and v2 are the mass and velocity of the plunger, and V is the recoil velocity. By plugging in the given values, you can solve for V.
To calculate the average force exerted on the plunger by the gun, you can use the equation:
F = m2a
where F is the force, m2 is the mass of the plunger, and a is the acceleration. By rearranging the equation and plugging in the given values, you can solve for F.
If the bullet is accelerated to its velocity in 10.0 ms, the force exerted on the gun can be calculated using the equation:
F = m1a
where m1 is the mass of the bullet and a is the acceleration. By plugging in the values and solving for F, you can compare it to the force exerted on the plunger.
