A small cart of mass m = 0.755 kg is moving at a constant speed v = 8.75 m/s on the inside of a vertical circular track with radius 4.35 m. (a) Calculate the period of the cart's motion. (b) Calculate the normal force (in Newtons) that the track exerts on the cart at its topmost point. (c) If the track wasn't there but the cart was moving with the same speed, period, and radius around an object in the center of the circle, purely due to the gravitational attraction between them, calculate the mass of that object in the center.
