A Ferris wheel rotates 12 times on for each ride. A passenger is 5 meters from the center of the wheel. The ride takes 10 minutes to complete. What is the angular speed (in radians/second) of the passenger?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.
