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

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/s

Final Velocity of Bird V = 2.5 m/s

acceleration a = -0.5 m/s²  ( as opposite to the fly direction)

Time T= 3 sec

Applying formula

V = U + aT

=> 2.5 = U + (-0.5)3

=> 2.5 = U -1.5

=> U = 4 m/s

the initial velocity of the bird before the gust of wind =  4 m/s

1. perpendicular

2. parallel

3. perpendicular

i would say true? if the unit was informational and it "refreshed your understanding", then true.
