- A2 Kg object moves on a track to the right at 10 m/s, and then reaches a circular depression. Assume the object stays on the track, and the radius of the track is 4 meters at the bottom of the circular depression. Also assume the bottom is 4 meters below the initial position of the object. There is no friction. 2 Kg 10 m/s When the object reaches the bottom of the circular depression, calculate the normal force that the track exerts on the object.Module 3 Item 1 Answer ASAP
