In coming to the conclusion that lightbeams are bent by gravity, Einstein reasoned that
 
  A) increased mass at higher velocities causes increased gravitational effects, so lightbeams moving at lightspeed should have gravitational effects.
  B) since all observers experience the same laws of physics, Newton's theory of gravity must apply to lightbeams.
  C) since lightspeed is the same for all observers, moving observers would observe that lightbeams bend.
  D) fast-moving observers would find that lightbeams bend, so gravity must also bend lightbeams.
  E) accelerated observers would find that lightbeams bend, so gravity must also bend lightbeams.

Question 2

Jason takes off across level water on his jet-powered skis. The combined mass of Jason and his skis is 75 kg (the mass of the fuel is negligible). Water exerts a force of 200 N on the skis.
 
  The coefficient of kinetic friction between skis and water is 0.10. Unfortunately, the skis run out of fuel after only 90 s. What is Jason's top speed? A) 150 m/s
  B) 240 m/s
  C) 24 m/s
  D) 90 m/s
