A boat of mass 250 kg is coasting, with its engine in neutral, through the water at speed 3.00 m/s when it starts to rain. The rain is falling vertically, and it accumulates in the boat at the rate of 10.0 kg/hr. using this formula: mb*vb/(mb+k0+t1) i got an answer of 2.86, but it's incorrect. it tells me im close, but wrong. do i need to convert the units or something?
