An amusement park ride consists of a rotating circular platform 11.4 m in diameter from
which 10 kg seats are suspended at the end
of 1.54 m massless chains. When the system
rotates, the chains make an angle of 32.3
◦ with the vertical.
The acceleration of gravity is 9.8 m/s
What is the speed of each seat?
Answer in units of m/s.

If a child of mass 29.2 kg sits in a seat, what is
the tension in the chain (for the same angle)?
Answer in units of N.

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
