An estimate of the minimum velocity required for a round flat stone to skip when it hits the water is given by (Lyderic Bocquet, “The Physics of Stone Skipping,” Am. J. Phys., vol. 71, no. 2, February 2003):
where M and d are the stone mass and diameter, ρw, is the water density, C is a coefficient, θ is the tilt angle of the stone, is the incidence angle, and
g = 9.81 m/s2. Determine d if V = 0.8 m/s. (Assume that M = 0.1 kg,
C = 1, ρw=l,000kg/m3, and ß= θ= 10°.)
