2. How does your value for ‘g’ compare to the accepted value of the acceleration of a free-falling object (9.81 m/s²). i am giving 100 points, I'm begging u to give the right answer

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
