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, = - 10 m/s, = - 10 m/s, = -2 m/s2, ( = 90o, = -0.4 rad/s, = -0.32 rad/s2. At this instant, determine

(a) The normal force between the cart and the track,

(b) The radius of curvature of the track.
