Yep. That's all you need to solve both parts.mandy9008 said:momentum?
Sure. What's the initial velocity and momentum before the rifle is fired?mandy9008 said:m1v1i + m2v2i = m1v1f + m2v2f
Right. Keep going. You're given the final speed of the bullet.mandy9008 said:velocity and momentum is 0
Mass 2 is the mass of the rifle (at least in part a). You'll have to figure that out from the given information.mandy9008 said:okay, so it will be
mass 1 is 0.0055kg? then what is mass 2?
mandy9008 said:okay, so
m1v1i + (0.0055 kg) (0 m/s) = m1v1f + (0.0055 kg) (260 m/s)
I am confused now
You switched them around. You have m2 as the mass of the bullet, which means that m1 is the mass of the rifle (for part a). That's fine.mandy9008 said:okay, so
m1v1i + (0.0055 kg) (0 m/s) = m1v1f + (0.0055 kg) (260 m/s)

To calculate the recoil speed, you can use the formula: recoil speed = (force x velocity) / mass. Make sure to use consistent units for force, mass, and velocity.
Yes, you can use the formula for any type of force, as long as the units are consistent. However, keep in mind that the force used in the formula should be the net force, which is the total force acting on the object.
The units used for force, mass, and velocity should be consistent. Common units for force are Newtons (N), for mass are kilograms (kg), and for velocity are meters per second (m/s).
The greater the mass of an object, the smaller the recoil speed will be. This is because the mass is in the denominator of the formula, so a larger mass will result in a smaller recoil speed.
Yes, the maximum recoil speed that can be achieved is the velocity of the object before the force is applied. This is because the object can only move as fast as the force is pushing it, and once it reaches its original velocity, it will stop accelerating.
