Three different-mass projectiles are launched from the top of a building each at different angles of elevation. Each particle has the same initial kinetic energy. Which particle has the greatest kinetic energy just as it impacts with the ground?
 a. The one launched at the highest angle of elevation.
  b. The one with the highest mass.
  c. The one with the lowest mass.
  d. They all will have the same kinetic energy on impact.

Question 2

A Hooke's law spring is compressed a distance d and is used to launch a particle of mass m vertically to a height h above its starting position. Under double the compression, the spring is now used to launch a particle of mass 2m. How high does the second mass rise above its starting position?
 a. h
  b. 2h
  c. 3h
  d. 4h
