I've been stuck on this problem for a while now, and have tried it several different ways, but with no results. This leads me to believe that I'm missing something obvious or simply approaching it from the wrong direction.
The moon subtends an angle of 0.5 degrees at the objective lens of a...

Since puck B is initially at rest, the initial linear momentum of the system is: m1*v
After the collision, the linear momentum will be equal to: m1*v1 + m2*v2
Since linear momentum is conserved, the initial and final linear momentums will be equal. Once you equate these, you can solve...
For some reason, I'm having trouble getting started on this problem:
A bullet of mass m is fired from a gun of mass M. If the gun can recoil freely and the muzzle velocity of the bullet (velocity relative to the gun as it leaves the barrel) is v_{0}, show that the actual velocity of the...
