A child lies on his back and raises his head up off the floor. When doing so, the total tension force in his neck muscles is 51.0 N. The same child now is sliding feet first down a water slide. The slide makes a circular curve, where the outside wall of the slide is vertical but the curve itself is in the horizontal plane, and the radius of the curve is 2.40 m. While sliding along this curve, the child's speed is 3.35 m/s. The child raises his head from the wall of the slide and holds it steady, looking forward. At this moment, what is the total tension (in N) in the child's neck muscles
