In a video game, a science-fictional “angry bird” is launched straight upwards by a high-velocity cannon from the surface of a planet far from Earth. The bird’s initial vertical velocity is 249 m/s (up). If gravity around this planet is a constant 11.2 m/s2, and the video game does kinematics correctly, how much time does it take the bird to reach the top if its trajectory?
