I am having some trouble with my physics homework. #1) A 300m-tall tower is built on the equator. How much faster does a point at the to of the tower move than a point at the bottom? #2) A 5m-diameter merry-go-round is initually turning with a 4.0s perio.d It slow down and stops in 20s. Before slowing, what is the speed of a child on the rim?
