Why not start with the work-energy theorem?xlogit3k said:No idea how to start this problem

Well, you know the initial velocity is 0 and the final velocity is 392 m/s.xlogit3k said:Wnet= 1/2mv^2(final)-1/2mv^2(initial)
i don't know what numbers to put in

But there is also something else you'll need. What is the very definition of work? (Hint: it's a function of force and displacement).
That's right! (Well, technically it's the dot product of force and displacement). Now you should have enough to solve the problem.xlogit3k said:force x distance
The force of a 17g bullet when accelerated in a rifle barrel is dependent on several factors, including the type of rifle and ammunition used, as well as the length and diameter of the barrel. In general, the force will be greater at the beginning of the acceleration and decrease as the bullet travels through the barrel.
The force of a bullet can be calculated using the formula F = ma, where F is the force, m is the mass of the bullet, and a is the acceleration. In this case, the acceleration is the rate at which the bullet's velocity increases as it travels through the barrel.
The force of a bullet in a rifle barrel is significant because it determines the velocity and energy of the bullet when it exits the barrel. A higher force will result in a faster bullet and greater potential for damage upon impact.
The force of a bullet can affect accuracy in several ways. A higher force can cause more recoil, which may impact the shooter's aim. Additionally, if the force is not consistent, it can lead to variations in the trajectory of the bullet, resulting in decreased accuracy.
The force of a bullet can be increased by using a more powerful rifle or ammunition, as well as by increasing the length and/or diameter of the barrel. However, it is important to note that increasing the force may also result in increased recoil and potential for damage to the rifle or shooter.
