Water falls without splashing at a X kg/s from a height H into a bucket of mass M. The bucket sits on a sacle. Determine the reading of the sacle as a function of time. I know the the sum of all forces is equal to the derivative of momentum with respect to time. Mg is the force at time = 0. The correct answer is mg + xtg + x*SQRT(2gH) I know F = dp / dt dp = F dt but I don't know what to do.
