Identify whether the following statements describe a change in acceleration. Explain your response answer them all plz b. A boat traveling east at 10 knots.
c. An airplane traveling north 600 miles per hour.
d. A person running at 5 meters/second along a curving path.

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.
