Inclined planes

The newest thing in slides is called the sky slide, like this one that allows you to slide down a 45 foot long sheet of glass, 70 stories high above Los Angeles. How fast would you be going when you got to the bottom? Lets find out...

 

First, what assumptions are we making?

 

What are the known quantities? What do we need to solve for?

 

What is our basic plan?

 

What kind of diagram is appropriate?

Now write the basic equations. Simplify them to our needs.

 

We can use the photo to approximate the angle.

 

Formulate your equations and solve completely algebraically before inserting known values.
