A satellite of mass 500 kg orbits the Earth with a period of 6000 s. The Earth has a mass of 5.98 x 1024 kg. (a) Calculate the magnitude of the Earth's gravitational force on the satellite.
 
  (b) Determine the altitude of the satellite above the Earth's surface.

Question 2

Two waves travel simultaneously through the same medium. The first wave is described by y1(x,t) = Acos(kx-t) and the second wave by y2(x,t) = B sin(kx-t).
 
  If the resulting superposition can be written as y(x,t) = C cos(kx-t + /5 ), what is the value of A/B?
  A)
 
  sin(/5 )
 
  B)
 
  cos(/5 )
 
  C)
 
  cot(/5 )
 
  D)
 
  sec(/5 )
 
  E)
 
  tan(/5 )
