Final answer:
Using the kinematic equation v = u + at, we find it takes 3 seconds for the bird to achieve a velocity of 6 m/s upward with an acceleration of 2 m/s^2. Therefore, the correct answer is C: 3 seconds.
Step-by-step explanation:
To determine how long it will take the bird to fly the total distance upward with an acceleration of 2 m/s2 to achieve a velocity of 6 m/s, we use the kinematic equation v = u + at, where 'v' is the final velocity, 'u' is the initial velocity (0 m/s since the bird starts from the ground), 'a' is the acceleration, and 't' is the time. Plugging in the values, we get 6 m/s = 0 + (2 m/s2 * t). Solving for 't' gives us t = 6 m/s / 2 m/s2 = 3 seconds.
To find the time it takes for the bird to fly the total distance upward, we can use the kinematic equation: vf = vi + at, where vf is the final velocity, vi is the initial velocity, t is the time, and a is the acceleration. Given that the final velocity is 6 m/s, the initial velocity is 0 m/s (since the bird starts from rest), and the acceleration is 2 m/s², we can solve for time:
t = (vf - vi) / a = (6 m/s - 0 m/s) / 2 m/s² = 3 seconds
Therefore, it will take the bird 3 seconds to fly the total distance upward.
Therefore, the correct answer is C: 3 seconds.
