To solve the problem, we need to show that the mass \( m \) of the largest stone that can be moved by the river can be expressed in the form: \[ m = \frac{k v^6 \rho}{g^3} \] where \( k \) is a dimensionless constant, \( v \) is the velocity, \( \rho \) is the density, and \( g \) is the acceleration due to gravity. ...
