Particle Motion on a Potential Energy Curve

Click For Summary
SUMMARY

The discussion focuses on calculating the speed of a particle with a mass of 3.0 kg as it moves along the x-axis, specifically at the position x = 14.0 m. The particle's potential energy U(x) is variable, and its initial velocity at x = 8.5 m is given as 2.273 m/s. The relevant equation for energy conservation, ET = mgh + 0.5mv², is utilized to determine the speed at the new position. Participants seek guidance on applying this equation correctly to find the solution.

The figure is not working, at least not for me.
