Figure 11-32 shows the potential energy U ( x ) of a solid ball that can roll along an x axis. The scale on the U axis is set by U s = 100 J. The ball is uniform, rolls smoothly, and has a mass of 0.400 kg. It is released at x = 7.0 m headed in the negative direction of the x axis with a mechanical energy of 75 J. (a) If the ball can reach x = 0 m, what is its speed there, and if it cannot, what is its turning point? Suppose, instead, it is headed in the positive direction of the x axis when it is released at x = 7.0 m with 75 J. (b) If the ball can reach x = 13 m, what is its speed there, and if it cannot, what is its turning point? Figure 11-32 Problem 8.

Solution Summary: The author explains how the law of conservation of energy can be used to find the P.E at the turning point and the total energy at x = 13 m.
Figure 11-32 shows the potential energy U(x) of a solid ball that can roll along an x axis. The scale on the U axis is set by Us = 100 J. The ball is uniform, rolls smoothly, and has a mass of 0.400 kg. It is released at x = 7.0 m headed in the negative direction of the x axis with a mechanical energy of 75 J. (a) If the ball can reach x = 0 m, what is its speed there, and if it cannot, what is its turning point? Suppose, instead, it is headed in the positive direction of the x axis when it is released at x = 7.0 m with 75 J. (b) If the ball can reach x = 13 m, what is its speed there, and if it cannot, what is its turning point?
Please solve and answer the question correctly please. Thank you!!
You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand? Ignore air resistance.
Help me make a visualize experimental setup using a word document. For the theory below.
