Fastest descent with 5 segments
- Jon Ingram
An object starts at rest at 'Start', and falls down the wire (passing through the kinks without losing any energy) until it reaches 'End'. What shape should the wire be to minimise the travel time? The wire is assumed to be smooth, so there is no friction slowing things down. g is 9.8 (i.e., we are on the surface of the Earth).
