## Homework Statement

I made a physics problem for a project that we had to do, but I do not know where to start.

Saruman’s plan to get the one ring involves disposing of the ring-bearer. To protect Frodo, Gandalf fights Saruman. In the following battle, Saruman pushes Gandalf 20 feet across the floor at a speed of 60 m/s. Before he hits the window, 8 foot fall Gandalf plants his staff into the ground which causes him to rotate around it.a) Determine the torque of gandalf as he rotates on his staff for 8 seconds if he weighs 120 kg.Saruman then throws a large book with a mass of 18.0 kg at gandalf who is then thrown out the window.b) What is his momentum before he hits the window and after he falls through, if the window falls along with gandalf, given that the mass of the window is 20 kg?c) What is the distance Gandalf is thrown out the window when he reaches the ground?

## Homework Equations

ω=v/r

I=mr^2

Torque=I*

**α**

KE=1/2I[/B]

KE=1/2I

**ω^2,**## The Attempt at a Solution

This problem involves many things, and I don't know where to start.
