Three balls are thrown off the top of a building, all with the same speed but with different launch angles (position is given in meters and time is given in seconds). Restart. The components of the initial velocities are given.

  1. Rank the three balls according to which one hits the ground first.
  2. Rank the three balls according to which one has the greatest speed the instant before impact with the ground.
  3. Now calculate the speed of each of the balls the instant before impact with the ground.
