In an amusement park ride called The Roundup, passengers stand inside a 19.0 m -diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane, as shown in ( Figure 1).

Imagine you are on an amusement park and on a train ride. At some point the train ride follows a horizontal circle of radius r = 5.00 m around a center “O”. At what magnitude of tangential velocity of the train carts do you have a centripetal acceleration with magnitude of 2.5g? g is the standard gravitational acceleration on the surface of theEarth.a. about 2.42 m/sb. about 123 m/sc. about 11.1 m/sd. about 19.8 m/s

A sprinter participating in the 200 m dash has to run around a track that has a circular arc with a radius of curvature of 26 m.  She completes the 200 m dash in 22.8 seconds at constant speed throughout the race. a) What is the magnitude of her centripetal acceleration in m/s2 as she runs the curved portion of the track?  b) What is the magnitude of her tangential acceleration in m/s2 as she runs the curved portion of the track?   c) What is the magnitude of her angular acceleration in rad/s2 as she runs the curved portion of the track?   d) What is the magnitude of her resultant linear acceleration in m/s2 as she runs the curved portion of the track?
