Suppose an outfielder throws a baseball with an initial speed of 12 m/s in a direction 30° up from the horizontal. Use a trajectory diagram to determine the height of the peak of its trajectory in reality. I suggest using a time step of Δt = 0.2s and a scale of 1.0 m (in reality) = 2.0 cm (on diagram).   The height of the peak of its trajectory in reality is ______ m.
