A sailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5 ᵐ/s² for 4s. After the wind stops, the sailboat is traveling to the left with a velocity of 3.0 m/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.
a. 5.0 m/s
b. 7.0 m/s
c. 10.0 m/s
d. 12.0 m/s
