What is the magnitude of the constant acceleration required to do this? O 7.5 m/5^2 6.6 m/s^2 8.9 m/s^2 9.9 m/s^2 5.6 m/s^2A 0.03 kg yellow marble is thrown horizontally at a speed of 5 m/s from a height of 4 m. Likewise, a 0.06 kg blue marble is thrown horizontally from the same height but at a speed of 10 m/s. Compared to the time it takes the yellow marble to reach the ground, the time it takes the blue marble to reach the ground is O one quarter as much O four times as much O the same O twice as much O half as muchA plane leaves the runway with a speed of 14.42 m/s eastward with respect to the still air when a wind of 4.11 m/s blows to the northwest. What will be the magnitude of the resultant velocity as it is affected by the wind? Express your answer in m/s and in two decimal places
