A boat of mass 250 kg is coasting, with its engine in neutral, through the water at speed 1.00 m/s when it starts to rain with incredible intensity. The rain is falling vertically, and it accumulates in the boat at the rate of 100 kg/hr .
What is the speed of the boat after time 0.500 hr has passed?
Is the component of the total momentum of the system parallel to the direction of motion still conserved?
What is the acceleration of the boat just after the rain starts?
Answers: 2
, b) Yes, c) 
![v(0.5\,h) = (1\,\frac{m}{s} )\cdot \left[\frac{250\,kg}{250\,kg+(100\,\frac{kg}{h} )\cdot (0.5\,h)} \right]](/tpl/images/0600/2687/045c9.png)
