Roller Coaster Rules

Physics
Let's get Rollin'
Loop # 1
We decided that our would roller coaster consist of two loops one hump since it is a requirement. The main goal is to find the velocity of the marble at three different locations using two differnt methods
This loop is measured to be the four inches tall and seven inches wide. The marble passed through the loop successfully. Its pillar is nineteen inches tall.
On to the next one
The gap between the previous loop and the next loop is measured to be...
Loop # 2
The second loop is measured to have a height of four and a half inches and a width of five inches. The pillar is measured to have a height of twelve and a half inches
Keep going
Almost there
The Hump
The hump's height is 1 inch. The width is 2 inches. A pillar was not needed.

Soo...
I think I failed. I tried my best to do this but
hopefully I didn't fail... But most likely, I did
fail.
