On a frictionless horizontal table, two blocks (A of mass 2.00 kg and B of mass 3.00 kg) are pressed together against an ideal massless spring that stores 75.0 J of elastic potential energy.
 
  The blocks are not attached to the spring and are free to move free of it once they are released from rest. The maximum speed achieved by each block is closest to: A) 6.71 m/s (A), 4.47 m/s (B)
  B) 4.47 m/s (A), 6.71 m/s (B)
  C) 5.48 m/s for both
  D) 6.12 m/s (A), 5.00 m/s (B)
  E) 5.00 m/s (A), 6.12 m/s (B)

Question 2

In Jules Verne's From the Earth to the Moon, scientists are launched from the surface of Earth by a cannon.
 
  With what speed would their capsule have to leave the cannon if the speed of the capsule is required to be zero m/s at the point between Earth and the Moon where their gravitational pulls on the capsule are equal? The mass of Earth is 5.97  1024 kg, the mass of the Moon is 7.35  1022 kg, the distance between Earth and the Moon is 3.84  108 m, the radius of Earth is 6.37  106 m, and G = 6.67 x 10-11 Nm2/kg2. A) 11,100 m/s
  B) 11,200 m/s
  C) 10,400 m/s
  D) 15,700 m/s
  E) 15,800 m/s

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
