a bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5m/s2 for 3s

Answer:4 m/s Step-by-step explanation:A bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5 m/s^2 for 3 s. After the wind stops, the bird is flying to the right with a velocity of 2.5 m/s.Assuming the acceleration from the wind is constant, what was the initial velocity of the bird before the gust of wind?Let say Initial Velocity of Bird = U m/sFinal Velocity of Bird V = 2.5 m/sacceleration a = -0.5 m/s²  ( as opposite to the fly direction)Time T= 3 secApplying formulaV = U + aT=> 2.5 = U + (-0.5)3=> 2.5 = U -1.5=> U = 4 m/sthe initial velocity of the bird before the gust of wind =  4 m/s
