  1. Atmosfear Winnie Wu, Jennifer Vu & Emily Chan Block 2-1

  2. There are 12 swings on the Atmosfear and it fits 2 people per swing. Each round takes 12 seconds. The radius of the swing is 15 meters. The mass of two people on a swing is 118kg. Find: • The kinetic energy of the two people at the top of the ride. • The efficiency of the ride if the input energy that the motor gives is 50000J.

  3. 1. 2π(15) 12 = 7.85 m/s KE= ½mv² = ½(118)(7.85)² = 3638.5 J = 364 x 10 J

  4. 2. Energy Output Energy Input Efficiency= × 100% 50000 J 12 ppl = 4166.7 J/person 3640 4166.7 × 100% = 87.3%
