G 2) The deceleration of a body in water due to hydrodynamic drag is a function of the body’s velocity. Assume that the acceleration due to hydrodynamic drag for a boat is given by: a = −0.05v 2 m s 2 Where v is the boat’s velocity. If the boat is moving at 10 m/s when the engine is shut down, find the boat’s velocity 4 seconds after the engine is shut dow
