Telemetry technology is used to quantify kinematic values of a 200-kg roller-coaster cart as it passes overhead. According to the system, r = 25 m, r . = 210 m/s, r¨ = 22 m/s²
, u 5 908, u . = 20.4 rad/s, u ¨ = 20.32 rad/s²
. At this instant, determine (a) the normal force between the cart and the track, (b) the radius of curvature of the track.
