Compute all parts of given problem:
Problem: An arrow is launched from a height of 1.21 m above the ground with an initial speed of 48.3 m/s and an initial angle of 35o above the horizontal. Assume air resistance is negligible.
Part A: At what time after the release of the arrow will the arrow be flying exactly horizontally?
Part B: What will be the maximum height the arrow will reach during its trajectory?
Please show all work and clearly explain each step.
