Realize I'm asking a lot of question today, but I'm working on a huge physics project and I'm not asking for answers, just some guidance where I'm stuck
A certain yo-yo can be modeled as a uniform cylindrical disk with mass M and radius R and a lightweight hub of radius...
One likely theory for the origin of the Moon is that it was formed by the impact of a Mars-sized object on the young Earth. How fast would the object have to be going when it hit the Earth to vaporize enough rock to make the Moon?
Consider a simple model of a dam. A reservoir of water behind the dam is filled to a height h. Assume that the width of the dam is L. As the reservoir behind a dam is filled with water, the pressure that the water exerts on the dam increases. Eventually, the force on the...
Show that the angular momentum in circular orbit around a mass
M can be written as functions of just the masses, the
orbit radius, and G.
L = r x p = r x mv
L = Iw
The Attempt at a Solution
I had no trouble showing that the total...
A certain yo-yo can be modeled as a uniform cylindrical
disk with mass M and radius R and a lightweight hub of
radius ½R. A light string is wrapped around the hub.
(a) First, the yo-yo is allowed to fall. Find the angular
velocity of the yo-yo when the string has...
