Homework Statement
I have a hill with a roller coaster cart on it and it goes down and around a loop-the-loop
the radius of the loop is 10m
Diameter=20m
What is the minimum speed the cart needs to go to keep it on the track?
There is no friction, what is the height of the hill?
Homework Equations
Vtop=sqrt rg
The Attempt at a Solution
to get the minimum speed the cart needs to go to keep it on the track is
Vtop= sqrt rg
=sqrt 10m(9.8 m/s^2)
Vtop=9.89 m/s ---------is this correct?
There is no friction, what is the height of the hill?
I don't know what to do for this problem
