Initial Speed of Bullet in Inelastic Collision

AI Thread Summary
In the discussion, the focus is on calculating the initial speed of a bullet fired into a wooden block using principles of physics. The bullet, weighing 5.5 grams, strikes a 22.6-gram block of wood that is initially at rest on a 1.5-meter tall post. After the collision, both the bullet and block land 2.5 meters away from the base of the post. The Conservation of Momentum is highlighted as a key principle to determine the final speed of the combined system post-collision, which then behaves as a projectile. The discussion emphasizes the application of these concepts to solve the problem without delving into extraneous logic or unrelated topics.

A 5.5 gram bullet is fired into a block of wood with a mass of 22.6 grams. The wood block is initially at rest on a 1.5 meter tall post. After the collision the wood block and the bullet land 2.5 meters from the base of the post. Find the initial speed of the bullet.

Keep this enclave free of such logic. This a place of no post count.
Madness runs in our blood!

Use The Conservation of Momentum to find the final Speed and the system will now move as a projectile
 

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
