## Falling Apple Kinematics

Here's a more interesting kinematics problem I found Recently while tutoring physics 1, it uses the kinematic equations in a system of equations to solve the problem. The most important thing to learn from this problem is that time is the same in any direction, and the same for any object (until you go really fast at least).

"An arrow is shot at an angle of 45 degrees above the horizontal. The arrow hits a tree a horizontal distance "D" away at the same height above the ground."

Part A: Find the Time of flight and Velocity at release.

Part B: If an apple falls from a distance "h" above where the arrow strikes, when (after the arrow is released) does it need to fall to be struck by the arrow?
