Problem Details

A particle in The graph shows potential energy as a function of distance. Distance is measured on the x-axis. Potential energy is measured from 0 to 5 joules on the y-axis. Two points are marked on the x-axis and are successively labelled as A and B. Point A is at the origin. Potential energy smoothly rises from 2 joules at A to 5 joules at the middle distance between the points. Then, it smoothly drops to 0 joules at B. has a mass of 100 g.

What minimum speed does the particle need at point A to reach point B?

What minimum speed does the particle need at point B to reach point A?
