I have a report to do on USB flash drives for uni. I was wondering if anyone knew the most popular material that is used in the making for the casing of these.
Some sort of plastic I know but I'm looking for the technical name for it.
A 1.2 block is tied to a string that is wrapped around the rim of a pulley of radius 7.3 . The block is released from rest.
Assuming the pulley is a uniform disk with a mass of 0.31 , find the speed of the block after it has fallen through a height of 0.50 .
