An amusement park ride consists of a rotating circular platform 10.2 m in diameter from which 10 kg seats are suspended at the end of 1.55 m massless chains. When the system rotates, the chains make an angle of 34.1 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 39.4 kg sits in a seat, what is the tension in the chain (for the same angle)? Answer in units of N. 013 10.0 points An aerobatic airplane pilot experiences weightlessness as she passes over the top of a loop-the-loop maneuver. The acceleration of gravity is 9.8 m/s. If her speed is 200 m/s at this time, find the radius of the loop. I Answer in units of km.
