A toy car, which has a mass of 2.0 kg, moves in a verticaly aligned circular track with constant speed as displayed in the image. Assuming that the circular track has radius 5.0 m, and the speed of the toy car is 10 m/s, find the magnitude of the normal forces NA and Ng exerted on the toy car by the surface of the circular track at points A and 8, respectively. Suppose that the gravitational acceleration is 10 m/s. O NA - 50 N and Ng - 25 N O NA = 30 N and Ng = 50 N O NA = 60 N and NB = 50 N O NA - 20 N and Ng - 50 N O NA = 60 N and Ng = 20 N O NA = 40 N and Ng = 80 N A toy car, which has a mass of 2.0 kg, moves in a verticaly aligned circular track with constant speed as displayed in the image.
