Mission Impossible III

Impossible or Possible?The Building Swing:
How fast was Ethan Hunt going when he reached the opposite building in Shanghai?
For this problem we will need to know the initial velocity in the Y direction, acceleration in the Y direction, and time.
Hunt began the swing at rest, meaning the initial velocity in the Y direction will be 0 m/s. If one ignores wind resistance, then Hunt's acceleration will be -9.8 m/s². The time it took Hunt to reach the opposite building is unclear, but we will assume it took about 6 s.

The Helicopter Chase:
How long did it take the enemies helicopter to hit the ground after it hit a windmill blade?
For this problem we will need to know the initial velocity in the Y direction, the final velocity in the Y direction, and the acceleration in the Y direction.
The helicopter was moving in the X direction, so one can assume its velocity in the Y direction was  0 m/s. The final velocity of the helicopter can only be estimated by the force with which it landed, wh…
