A bullet with some mass, m, and initial speed, vi, collides with a wooden block of mass M that is hanging at the end of a light rope. The bullet imbeds itself in the block and the block and bullet swings upwards reaching a maximum height of h above the initial point of the collision. a. A scientist can measure the masses and the height, show that the initial speed can then be calculated from the following equation: vi= (m+M)/m×root...

2. Consider the following physical situation: A spring that obeys Hooke's Law and has a known/given spring constant k has been compressed to half of its equilibrium length. It's anchored at one end while the other end pushes (but is not attached to) a block of mass m in the horizontal direction. The block is initially held in place. Once released, the block accelerates to the right and achieves a final speed of ve at the point when it leaves...

2 moles of compressed air (diatomic gas) in a cylinder under the initial condition T1=573K p1=500kPa. Found v1=0.019m^3 but can not remember then how to find V2. I think that it has something to do with T1=T2 condition then P2 can be found.... but stuck on how to proceed so with FULL written explanations with working would be much appreciated!
