When reading a compact disc, the player begins by reading theinformation near the center of the disc by rotating the CD at 450rpm. However, as it reaches the information at the edge of thedisc, the CD only revolves 200 rpm. If it takes 60 minutes to readthrough the disc:
a) what is its angular acceleration ( assume itsconstant)
b) What is its rate change of the CD's angular momentum?(treat the cd as a solid disc that is 120mm in diameter and has amass of 15g)
A 0.413 kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 24.6 N/m. The block rests on a frictionless surface. A 0.0500 kg wad of putty is thrown horizontally at the block, hitting it with an i..
