DRINKING WATER ON THE ZOOMERANG
BY CALEB, TIM, PAT, AND SOF
The scientific question we are trying to answer is can a person drink water from a water bottle while going through the loop of a roller coaster

EQUATIONS USED
- To find the normal force at the top of the loop, we used Fn + Fg = ma ; so Fn = mv^2/r - mg
- To find the velocity of the coaster at the top of the loop, V = 8 times the square root of h-2r

OUR THEORY
- We found out that Fn = 2.89N
- Because the net centripetal force is pushing the water out of the circle,the water in the water bottle would be going away from the earth while you are upside down
In conclusion, no you would not be able to drink water at the top of a loop in a roller coaster because the force of gravity is less than the centripetal force, so the water would be pushed towards the sky.
