Can you please help me out with the second part of this question? I got the first two parts. Its PART C that I am not getting. Thanks!

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.

Part A

What is the speed of the boat after time 2.00 hr has passed? Assume that the water resistance is negligible.

Part B

Now assume that the boat is subject to a drag force F_d due to water resistance. Is the component of the total momentum of the system parallel to the direction of motion still conserved?

Part C

The drag is proportional to the square of the speed of the boat, in the form F_{\rm d}= 0.5 v^2. What is the acceleration of the boat just after the rain starts? Take the positive x axis along the direction of motion.

Express your answer in meters per second per second.

Its Part C that I am not getting. Please help. Thanks!!

Thank-you very much for all your time and effort!!
