Question

A boat of mass 250kg is coasting, with its engine in neutral, through the water at speed 1.00m/s when it starts to rain with incredible intensity. The rain is falling vertically, and it accumulates in the boat at the rate of 100kg/hr . the drag is proportional to the square of the speed of the boat, in the form F_{ m d}= b v^2 where b = 0.5 Ncdot s^2/m^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.

Explanation / Answer

-2.11*10^-3 m/s^2. Don't listen to them. It is a correct answer
