Homework Statement
A) An amusement park ride consists of a rotating
circular platform 10.8 m in diameter from
which 10 kg seats are suspended at the end
of 2.34 m massless chains. When the system
rotates, the chains make an angle of 29.4◦ with
the vertical.
The acceleration of gravity is 9.8 m/s2 .
What is the speed of each seat?
Answer in units of m/s.
B) If a child of mass 42.6 kg sits in a seat, what is
the tension in the chain (for the same angle)?
Answer in units of N.
Homework Equations
∑F=ma_(c)= m (v^2/r)
The Attempt at a Solution
If this where talking about the string starting from origin of pole, wouldn't be that hard. But since they added the top diameter, I am not sure how to tackle this problem.
